docs(telemetry): path-qualify legacy dashboard names for check-rename

`.github/scripts/rename/docs.sh` is a migration script, not a check: the
`check-rename` workflow runs it and then fails if the tree changed. Its
rule `s@([^/+-])rippled@\1xrpld@g` rewrites `rippled` unless the preceding
character is `/`, `+` or `-`, so the backtick-quoted historical filenames
added by 3153f3ef56 (`` `rippled-*.json` ``, `` `rippled-alerts.yml` ``)
were rewritten and the check failed on both plan docs.

Refer to those historical names by their path-qualified form
(`dashboards/rippled-*`, `prometheus/rippled-alerts.yml`) instead. The
leading `/` exempts them from the rule, which is the form the rest of the
repo and the surrounding lines in these same files already use. No meaning
is lost -- the notes still record which commit renamed what.
