Gae24 09bb43ed8d script: check if resolved module specifier starts with the specifier of the imported maps (#42668) ...

After debugging some of the failing tests, it appears spec text is
wrong.
Inside [merge existing and new import
maps](https://html.spec.whatwg.org/multipage/#merge-existing-and-new-import-maps)
algorithm, when checking which imports needs to be ignored,
specification will check if each _specifier_ of _newImportMap's imports_
will override any specifier of [resolved module
set](https://html.spec.whatwg.org/multipage/#resolved-module-set), by
checking if specifier starts with `record.specifier`.

Since each specifier gets normalized before they are inserted in the
resolved module set, the are cases where the check fails and we end up
overriding a module resolution.

This was an oversight, since for _newImportMap's scopes_ specification
performs the right check:
`specifierKey is a code unit prefix of record's specifier;`

Testing: More tests are now passing
