Values coming from `${{ }}` expressions were interpolated directly into
`run:` scripts, so GitHub substituted them into the shell source before
bash parsed it. A commit title containing a double quote broke the
"Write step summary" step of the bundle build with a syntax error, and
the same pattern allowed arbitrary command execution on the
self-hosted runners.
Pass every expression used inside `run:` through step/job `env:` and
reference it as a quoted shell variable instead. Use the runner's
default variables (GITHUB_RUN_ID, GITHUB_REPOSITORY, ...) where the
value comes from the `github` context.
Also validate `plugin_name` in plugins-deploy-package.yml against
`^[a-z0-9][a-z0-9-]*$`, since it is free-form and reaches paths,
worker names, GITHUB_ENV and action inputs.
Affected workflows: build-bundle, build-docker,
build-docker-admin-console, plugins-deploy-package,
plugins-deploy-api-doc, plugins-deploy-styles-doc, release, tests-e2e.
