This would overwrite state from the server, it was breaking the server-provided localized strings previously.

The localized strings weren't working correctly before because the server-provided state was being overwritten with empty strings.
This form will work in Gutenberg but requires #65129 for it to work in Core.
There should be fallback code here to use the localized strings from Interactivity API state.

With the latest changes to use the localized fallback strings (passed via Interactivity API), if I disable this filter it correctly uses the those strings as a fallback.
#65129 proposes adding this filter to Core.

What?
Change the Interactivity Router a11y implementation to use the a11y Script Module introduced in #65101.
The a11y Script Module will be used in Gutenberg only and if it cannot be loaded, the Interactivity API fallback will be used.
Builds on:
WordPress/wordpress-develop#7304 implements the same script data passing for translated strings in Core.
Why?
Instead of its own 1-off implementation, shared a11y functionality can be used.
Testing Instructions
Enable client side navigation, for example in the query block turn off the "force page reloads" option.
With the proper accessibility set up, for example macOS voiceover, "Page loaded." should be announced when navigating.
Alternatively, you can inspect the DOM with something like this in a console preview:
