EQ2Parser 0.3.3

release: move the update feed onto the (now-public) main repo

Consolidate distribution: releases publish to VortexUK/EQ2Parser instead
of the separate EQ2Parser-releases repo, and the in-app updater reads the
main repo. Main-repo publish uses the workflow's GITHUB_TOKEN (same-repo,
no PAT).

v0.3.3 is the transitional build: it's ALSO published to the old
releases repo (RELEASES_PAT) so installs still pointing at that feed
(<= v0.3.2) find v0.3.3 and migrate onto the main feed. Once testers are
on v0.3.3+, the transitional step + RELEASES_PAT preflight come out and
future releases go to the main repo only.
