feat: Include/ Exclude file types from file search

[kplates]

This pull request introduces two new actions: ExcludeFileTypeFromSearchAction and IncludeFileTypeInSearchAction. These actions allow users to modify search patterns by excluding or including specific file types directly from the search result file context menu.

How to test

• Create a new repo or directory
• Add a few files with with different file types but some common value, we can also have files such as .spec.ts or further dot notation such as some.file.test.spec.ts
• Open search explorer and search for common value
• In the results list right click and select either Include or Exclude File Type From Search
