Subject: [PATCH] fix(webhook/discord): fixed username cannot be empty error
 (#35412)

username field is not required by discord and used to override the
default username. sending it as blank causes a 400 error. it should be
omitted instead when it's not set.

Ref:
https://discord.com/developers/docs/resources/webhook#execute-webhook-jsonform-params

Closes #35411
