Optimise default glue paths in settings

[kieran-ryan]

🤔 What's changed?

• Optimised default glue paths to merge repeated patterns to improve performance

⚡️ What's your motivation?

• As the extension performs a complete reindex on code changes for specified glob paths, it is important that these paths are optimal for best performance
• Code volume is reduced considerably, making it clearer which file extensions are expected under common paths

🏷️ What kind of change is this?

• :bank: Refactoring/debt/DX (improvement to code design, tooling, etc. without changing behaviour)

Benchmarked the fast-glob globbing library used by the Language Server through the node-glob benchmark.

Negligible difference for synchronous operations and interestingly the existing pattern appears to be around 17% faster (0.069s -> 0.081s); which is fairly insubstantial and may be a favourable tradeoff for a simplified default configuration. Though present performance constraints (#152) must also be considered.
