Add --no-git-checks when publishing from pnpm

[gndelia]

Using pnpm publish requires the package to be deployed from a branch. See publish docs.

This is a problem because libraries are released with tags. pnpm doesn't support this - the pnpm publish command just fails. See pnpm/pnpm#5894

The only workaround is adding the flag --no-git-checks. Disabling this check will disable these 4 checks on publish time (none of these are really relevant):

• Clean working tree (GIT_UNCLEAN) — runs git status --porcelain and fails if anything is uncommitted or untracked. In your run this check already passed before the branch error.
• HEAD attached to a branch (GIT_UNKNOWN_BRANCH) — reads .git/HEAD, then falls back to git symbolic-ref --short HEAD. Fails when HEAD is detached. This is the one that broke the release.
• Branch matches publish-branch (GIT_NOT_CORRECT_BRANCH) — compares the branch name against master|main by default. On a mismatch it asks for interactive confirmation, so with no TTY it fails regardless.
• Local history matches the remote (GIT_NOT_LATEST) — runs git rev-list --count --left-only @{u}...HEAD and fails if the upstream is ahead. A detached HEAD has no upstream, so the command errors, the catch swallows it, and the check returns clean. It is already a no-op in CI.

(Yup - that's AI ☝🏽 )

It seems we can safely enable it to allow using pnpm for publishing.
