Adjust Vale rules to ignore links

[Tokesh]

Description

Updated the process_file method to remove markdown links, leaving only their text content. This ensures the tool processes description and x-deprecation-message fields cleanly, aligning with Vale style-checking requirements.

1. Add tests, make sure there's one with 1 link and 2 links to https://github.com/opensearch-project/opensearch-api-specification/tree/main/tools/tests/prepare-for-vale.
2. Extract line.replace(/\[([^\]]+)\]\([^)]+\)/g, '$1') into a method, similar to prune_vars, maybe something descriptive like remove_links.

One more place where the transformation needs to be applied, see below.

Iterate till unit tests and linter are green (this repo uses a slightly different convention that the default TS with variable_names).

Add an integration test to https://github.com/opensearch-project/opensearch-api-specification/blob/main/tools/tests/prepare-for-vale/fixtures.

The way this works is that we remove all text that doesn’t need to be checked.

So, you have to replace the text with an equal number of spaces otherwise the comments from the tool appear in the wrong place on GitHub.
