feat: support extra head tags, extension to #1145

[toteto]

Summary

This PR is extension to #1145 to simplify the approval/merge process.

The change is that it introduces additional types to the head config attribute. This addition enables better per-page headers, in a sense plugin header support.

The immediate benefit i see in addition to #1145 is less duplication of tags that are to be only for a subset of the pages.

It seems the lockfile should be update to pass CI, you can rebase main branch and update it.
