Pin the tree-sitter version in requirements <0.22

[DNGros]

There are a several issues noting the breaking changes introduced by treesitter 0.22 (eg, #64 and #67). There is the PR #65 to fix this.

Ideally, some fix would be implemented, but I understand that is complicated.

As a quick fix perhaps consider pinning the the version of tree-sitter in the to be <0.22?
