feat(host-rules): ignore URL credentials when matching matchHost
`matchesHost()` compared the raw href of the searched URL against
`matchHost`, so a URL carrying `user:pass@` userinfo (often a literal
placeholder such as `${USER}:${PASS}@`) never matched a `matchHost`
without credentials, including path-scoped ones. Callers worked around
this by stripping `username`/`password` off the URL by hand before
calling `hostRules.find()`.
- Add `stripUrlCredentials()` to `lib/util/url.ts`, returning the URL's
`href` without userinfo (or `null` if unparseable), covered by
`lib/util/url.spec.ts`.
- `matchesHost()` in `lib/util/host-rules.ts` now strips credentials
from the searched URL before comparing it against an HTTP(S)
`matchHost`, so `hostRules.find()` ignores userinfo on every caller's
URL. Covered by new cases in `lib/util/host-rules.spec.ts` (a
`matchHost` rule matches a URL carrying `user:pass@`, including a
path-scoped `matchHost`).
- Remove the hand-rolled strip in
`lib/modules/datasource/pypi/host-rules.ts`'s
`findPypiIndexCredentials()`, now redundant since `find()` does it.
`lib/modules/datasource/pypi/host-rules.spec.ts` already covers this
behaviour and needed no changes.
This is strictly additive: more URLs match `matchHost` than before,
and nothing that matched before stops matching.
