First line actionlint error message, do not contain [actionlint] .

Start by reproducing the issue with the efm-langserver configuration and the tsuyoshicho/action-test-repo test case, comparing yamllint and actionlint diagnostics. Trace where the configured prefix is applied to lint-formats output; done when actionlint diagnostics include [actionlint] without changing the existing yamllint behavior.
