Confusing xref for HostResolveImportedModule

[Ms2ger]

The definition of HostResolveImportedModule links to ES but implements the version in import assertions, which took me a minute to find. It would be better to link to the latter, I think.

Although this is a minor editorial change and would probably be fine, it's worth noting there is a proposal to be presented at the next TC39 meeting for refactoring all the host module hooks into a single hook, which which ultimately invalidate such a change anyway.

A PR from anyone fixing this would be very welcome in the meantime.

I would be interested in picking up this small, soon obsolete contribution, in order to practice my PR on some open source code!
