feat: enable navigation to hashes

[iisakkirotko]

Previously this was not officially supported, and would only work when moving within a page, or when initially loading a page with SSG enabled.

If I go:
http://localhost:8765/documentation/advanced/enterprise/oauth
and click on say 'Configuring Fief' i navigate to it, but the hash does not change in the address bar (80% of the time).
If I then click it again, the hash does change.
I scroll up a bit, and click the https link with the hash to
http://localhost:8765/documentation/getting_started/deploying/self-hosted#https
That works seems to work, as well as navigating back, but it might be good to check after fixes.
I wonder if the problem is related to having 2 state attributes?
