Bump tree-sitter version to 0.23.0

Separate PR from #6076 to update tree-sitter to a newer version after adding tree-sitter-systemverilog CI jobs.

For some reason pip cannot find the latest tree-sitter version (https://pypi.org/project/tree-sitter/):

ERROR: Could not find a version that satisfies the requirement tree_sitter==0.23.0 (from versions: 0.0.1, 0.0.2, 0.0.3, 0.0.4, 0.0.5, 0.0.6, 0.0.7, 0.0.8, 0.0.9, 0.0.10, 0.1.0, 0.1.1, 0.2.0, 0.2.1, 0.2.2, 0.19.0, 0.20.0, 0.20.1, 0.20.2, 0.20.3, 0.20.4)
ERROR: No matching distribution found for tree_sitter==0.23.0

Might it have to do with python version?

On the other hand, tree-sitter-verilog seems unmaintained. There is an open PR from some months ago to update it to version 0.21: tree-sitter/tree-sitter-verilog#76
