fix(injected): parse injections

[folke]

On nightly, the injected formatter doesn't work.

parse(true) needs to be used to parse injections.

Caused by upstream change: neovim/neovim@2ca076e

[folke]

Disabled the diagnostic to pass the typecheck github action.
This new param is available on nightly, but not on stable
Stable doesn't have any parameters, so it's safe to always pass true

Agh, of course nightly. Thanks for the fix!

[folke]

Thanks for merging! :)
