feat: specify abi version for generate on newer ts cli

Browse source 
Check tree-sitter CLI version and if > 0.20.3 and generating a parser
from grammar, use `--abi=vim.treesitter.language_version`.

Besides being able to opt-in to newer ABI benefits, this is a necessary
workaround for an upstream bug with 0.20.3, where `parser.h` is not
generated if the (optional) `--abi` flag is omitted.
