Looks like most of your problem is your tags line.

For your "stable" builds, try something like:

on:
  push:
    tags:
      - '*.*.*'
      - '!*.*.*-*'

For your developmental builds, try something like:

on:
  push:
    tags:
      - '*.*.*-*'

Note the '!*.*.*-*' bit for the stable file. The ! means to ignore tags that match expression that follows, so you're explicitly telling the stable file to ignore developmental builds.

You don't need your add-on's name in tags. The packager does that and it's kind of redundant. So keep them simple, like "v2.0.4" or "v2.0.4-beta". If you must do it, make sure you include it in your tag lines for your workflows. The tag lines match the name of tags (regex-ish), so you'd do something like:

      - 'GuildBankSnapshots-*.*.*'
      - '!GuildBankSnapshots-*.*.*-*'

Etc.
