Addition of fork reference / Feature improvements (Sidebar & short.io) in README file.

[hk151109]

Hi,

I’ve been a fan of the minimalism of textarea.my and recently created a fork over at hk151109/textarea that adds some utility for power users.

I'm opening this PR to add a link to this fork in the README. My version introduces several key features:

Sidebar & Document History: Users can now view and switch between their previous documents directly from a sidebar, making it easier to manage multiple notes.

short.io Integration: For documents with large content (where the URL hash becomes unwieldy), I've integrated short.io to generate clean, manageable short URLs.

Regarding a full PR for these features:
I haven't raised a PR for the code changes yet because I modified the deployment workflow for my own setup. However, if you're interested in merging these features, I’d be happy to revert the deployment logic to your original configuration and raise a clean PR for the Sidebar and short.io functionality.

Best,
Harikrishnan Gopal

The phrase "for managing url of large documents" has a grammatical issue — "url" should be capitalized ("URL") and the phrase reads awkwardly. A clearer phrasing would be something like "for managing URLs of large documents."
