eclass/tree-sitter-grammar: fix ABI autodetecton

  Some grammars packages (like, for example, tree-sitter-agda) uses
  different versioning scheme from vast majority of grammars in
  tree-sitter github organization.

  Also, third-party grammars doesn't follow tree-sitter versioning.

  Also, some grammars (like tree-sitter-haskell, for example) only had
  old release tagged, but having compatible and useful grammars in
  current HEAD.

  Also, some grammars like tree-sitter-verilog, even have only v0.0 tag.

  So, instead of assuming grammar ABI version based on ${PV} (ver_test)
  we decided to take ABI version drectly from source code.
