chore: use upstream update automation

[mbevc1]

mislav/bump-homebrew-formula-action@v4 GHA is currently broken due GH endpoint http reposnse changes. We use upstream automatic updating now and shouldn't try to manually publish: Homebrew/homebrew-core#284321

Review: Remove manual Homebrew formula bump from release workflow

• Run static analysis (go build, go vet, go mod tidy)
• Review the diff
• Post review findings

Static Analysis

All checks pass cleanly — go build ./..., go vet ./..., and go mod tidy report no issues. This is expected since the change is workflow-only.

Code Review

The change looks correct and clean. Two commits that:

1. Remove the homebrew-pr job (the mislav/bump-homebrew-formula-action@v4 step + harden runner + env config) — 18 lines
2. Remove homebrew-pr from the notify-finish job's needs list — 1 line + trailing comma fix

Verified no dangling references: After this PR, no remaining references to homebrew-pr or COMMITTER_TOKEN exist in any workflow file. The other homebrew references in install-script-tests.yml are unrelated (they test Homebrew installation, not formula publishing).

No issues found:

• The notify-finish needs array is correctly updated — homebrew-pr is removed and the remaining entries are properly formatted
• No jobs depended on homebrew-pr other than notify-finish, so the dependency graph is intact
• The rationale is sound: upstream Homebrew autobump (homebrew-core#284321) handles this, and the action is broken anyway

Housekeeping Note

The COMMITTER_TOKEN secret is no longer referenced anywhere in workflows after this change. You may want to remove it from the repo's GitHub Secrets as cleanup.

LGTM — straightforward, well-scoped removal. Nice cleanup.
