Most workflow files are already well formatted, but to make it easier to
keep it that way, we can add yamlfmt.
I personally have a preference for non-indented arrays for YAML, but
wanted to avoid bigger diffs here - the status-quo clearly are indented
arrays.
Some changes are made manually to the get-merge-commit action and the
issue templates. Those would otherwise make yamlfmt misbehave on those.
25.11 is the current unstable, while 25.05 was promoted to stable and 24.11 is on its way to deprecation.
