Bump gopkg.in/ini.v1 from 1.61.0 to 1.62.0

This uses String.replace() instead of String.replaceAll().

Closes T811

This re-uses the HTMLContent feed for the full HTML content in the RSS
feed, instead of again generating HTML from Markdown.

This keeps things more consistent throughout the application and reduces
work when rendering the feed.

Dockerfile/docker-compose fixes

remove unnecessary var in account.go

Updates versions and uses maria DB instead of sqlite in the
docker-compose. Also fixes things related to networks, generating
config, etc.

When connecting to a generic OAuth provider, you are never sure what object you'll be receiving from the userinfo endpoint (it isn't actually specified anywhere). So this commit adds mapping values to the generic oauth configuration section of config.ini, allowing the user to specify which keys in the remote endpoint it expects to read the UserID, Username, DisplayName, and Email from. Default values if unspecified remain as they were before this commit.

Adding scope field to generic OAuth

Drop the /tags/{tag} route

Automatically resize CSS editor

Fix escaping in post summary

Some OAuth providers (like Mastodon) do not use the default
"read_user" scope, instead offering a custom scope. The config.ini
for generic OAuth now contains a "scope" field, allowing the admin
to set the scope manually (it defaults to "read_user" if blank).

Fix header spacing on pinned posts

Fix removal of query parameters on youtube embed links
