[Pkg-rust-maintainers] Bug#1082544: Bug#1082544: rust-tree-sitter: please upgrade to v0.22

[Peter Green]

I see that in addition to updating to 0.22, jamessan has restructured
the tree-sitter packaging in experimental to take it out of the rust
team and move to a single source package (tree-sitter) for all the
tree-sitter-* packages.

Looking through the reverse dependencies I see

sdml - maintained by Jonas, already broken and not in testing.

tree-sitter-sdml - maintained by Jonas

turtleformat - maintained by Jonas, caught up in oxigraph issues, scheduled for autorm

Jonas, can you investigate the compatibility of your packages
with the new tree-sitter?
