Added markdown linting to pre-commit hooks

[Shrishti1701]

This PR adds Markdown linting to the pre-commit hooks to ensure all .md files follow proper formatting standards. This helps maintain consistency and improves readability across the repository.

• Changes Made

Updated .pre-commit-config.yaml to include markdownlint.
Removed unnecessary lines and reformatted the configuration file.
Installed and tested the pre-commit hook to ensure it runs correctly.

• How to Test

1. Install pre-commit hooks (if not already installed):

pre-commit install

2. Run markdown linting on all files:

pre-commit run markdownlint --all-files

3. Check if all markdown files comply with linting rules.

• Expected Outcome

Markdown files should follow the correct formatting.
pre-commit run --all-files should pass without errors.

This PR seems to remove all the other linters, which isn't going to work for us.

I’ve resolved the issue related to the failing test. The "Tests that may fail due to network or HTML" error has been addressed. Kindly check the updated status and let me know if anything else needs attention.

@terriko I am just not able to understand whats the issue with the workflows each time they are showing diif errors.Could you guide me in how to resolve this.

The Markdown linter has been acting inconsistently, and after discussing it, we agreed it’s better to hold off on merging until it’s more stable. For now, I’m closing this out so I can focus on other contributions without being blocked.
If anyone wants to revisit this once the linter's in better shape, feel free to pick it up!
