This PR touches the most interesting part of the "template refactoring".
1. Unclear variable type. Especially for "web/feed/convert.go":
sometimes it uses text, sometimes it uses HTML.
2. Assign text content to "RenderedContent" field, for example: `
project.RenderedContent = project.Description` in web/org/projects.go
3. Assign rendered content to text field, for example: `r.Note =
rendered content` in web/repo/release.go
4. (possible) Incorrectly calling `{{Str2html
.PackageDescriptor.Metadata.ReleaseNotes}}` in
package/content/nuget.tmpl, I guess the name Str2html misleads
developers to use it to "render string to html", but it only sanitizes.
if ReleaseNotes really contains HTML, then this is not a problem.
The code was just copied&pasted, it causes problems now.
There are a lot (for every package) broken translations. eg:
```
# en-US
conda.documentation = For more information on the Conda registry, see
<a target="_blank" rel="noopener noreferrer" href="%s">the documentation</a>.
# fr-FR (and many languages)
conda.documentation=Pour plus d'informations sur le registre Conda, voir
<a target="_blank" rel="noopener noreferrer" href="https://docs.gitea.io/fr-fr/packages/conda/">la documentation</a>.
```
To resolve the problem fundamentally, use a general string, and trigger
the re-translating on Crowdin side.
And, it should really really really avoid introducing too much
copied&pasted code .......
The default command to setup a NuGet registry from the command line is:
```
dotnet nuget add source --name Gitea --username your_username --password your_token <gitea-origin-url/>
```
The feed name `Gitea` is hard-coded into the command template, so each
registry will by default have the same feed name. I know templates can
be overridden using the `custom` folder. But in my opinion, it's a good
practice to make a slight change in the default template to make the
feed name more context specific:
```
dotnet nuget add source --name {{.PackageDescriptor.Owner.Name}} --username your_username --password your_token <gitea-origin-url/>
```
This PR follows:
* #21986
* #22831
This PR also introduce customized HTML elements, which would also help
problems like:
* #17760
* #21429
* #21440
With customized HTML elements, there won't be any load-search-replace
operations, and it can avoid page flicking (which @silverwind cares a
lot).

# FAQ
## Why the component has the prefix?
As usual, I would strongly suggest to add prefixes for our own/private
names. The dedicated prefix will avoid conflicts in the future, and it
makes it easier to introduce various 3rd components, like GitHub's
`relative-time` component. If there is no prefix, it's impossible to
introduce another public component with the same name in the future.
## Why the `custcomp.js` is loaded before HTML body? The `index.js` is
after HTML body.
Customized components must be registered before the content loading.
Otherwise there would be still some flicking.
`custcomp.js` should have its own dependencies and should be very light,
so it won't affect the page loading time too much.
## Why use `data-url` attribute but not use the `textContent`?
According to the standard, the `connectedCallback` occurs on the
tag-opening moment. The element's children are not ready yet.
## Why not use `{{.GuessCurrentOrigin $.ctx ...}}` to let backend decide
the absolute URL?
It's difficult for backend to guess the correct protocol(scheme)
correctly with zero configuration. Generating the absolute URL from
frontend can guarantee that the URL is 100% correct -- since the user is
visiting it.

* Refactor `i18n` to `locale`
- Currently we're using the `i18n` variable naming for the `locale`
struct. This contains locale's specific information and cannot be used
for general i18n purpose, therefore refactoring it to `locale` makes
more sense.
