* Fix docs workflow: replace missing .nvmrc with explicit node version

The .nvmrc file was removed but the docs workflow still referenced it,
causing the Documentation CI job to fail on every push to main.

* Request workflows permission for Copybara GitHub App token (#504)

* [gha] Add workflows permission to Copybara GitHub App token

The Copybara push to webdev was failing because the token lacked
workflows permission, which is required to push branches that
include changes to .github/workflows/ files.

* [gha] Remove --nogit-destination-rebase from Copybara to fix workflow push error

The Copybara push to webdev was failing because the stale PR branch
had a diff including .github/workflows/js.yaml changes (from main
moving since the branch was created). Removing --nogit-destination-rebase
lets Copybara rebase on latest main so the PR only diffs js/ files.

* [gha] Request workflows permission for Copybara GitHub App token

The Copybara push to webdev fails because --nogit-destination-rebase
keeps the PR branch on a stale base, causing the branch diff to include
.github/workflows/js.yaml changes. Removing the flag isn't an option
(it causes merge conflicts — see PRs #365, #380, #448, #449).

Instead, request workflows:write permission on the token so the push
can include workflow file diffs. The LIGHTSPARK_COPYBARA GitHub App
also needs workflows permission enabled in its app settings.
