[CI] implementation: Woodpecker based CI (squash)

Upgrade xgo to Go v1.20 for building binaries

(cherry picked from commit 6308c776b6)

[CI] v1.20: switch PR check from Woodpecker CI to Forgejo Actions

The PR checks for v1.19 still rely on Woodpecker CI. Keeping
.woodpecker in v1.20 while both Woodpecker CI & Forgejo Actions are
enabled would dupicate the checks.

The release process in releases remains Woodpecker CI.
