Implement hook_help()

I would like to work on this issue. I will implement hook_help() in the media_entity_link.module file to provide basic module usage information on the help page, following the API documentation.

Created the help page content for the Media Entity Link module by restructuring it with headings and paragraphs for better readability, and including a brief description, usage instructions, and references to the online documentation.
Here is the ss of the help page.

phpcs and phpstan issues were coming up in my MR, fixed those as well.

Why you have reverted hook attribute? Also revert phpcs and phpstan fixes.
Moving back to Needs work

Added. hook_help for the module.

@danrod rest looks fine, moving into RTBC

It's alright, let's bypass it for now, let's do it like that for now, I'll merge if to the 2.0.x if you don't mind @d.fisher , @dishabhadra , @vladimiraus
