Index failure with partial Python parameter match

[kieran-ryan]

🤔 What's changed?

• Refined tree-sitter query for Python Parameter matches

⚡️ What's your motivation?

• Fixes Cannot index Python glue files containing 'name' keyword arguments #181

The Parameter Type tree-sitter query for Python allowed three optional keyword arguments, 1 for the name argument and 2 for the regular expressions argument in two different formats (string and concatenated-string).

This works fine with valid parameter type definitions using the keyword arguments in the order in which they are declared. However, the query fails in the following scenarios:

• The keyword arguments order is in reverse order. This fails to detect the parameter type but does not prevent reading from that glue file or other glue files.
• Any Python callable with either of name or regexp as keyword arguments yields a partial match (as the query specifies more arguments as optional), however the language service requires both and yields an unhandled exception as a result which prevents reading from all glue files entirely.

🏷️ What kind of change is this?

• 🐛 Bug fix (non-breaking change which fixes a defect)
