Enhance connection string update instructions in README

[JayanthT7]

Hi @hishamco , I’ve updated the README with LocalDB and standard SQL connection string examples to help new developers get set up faster. Please let me know if any changes or improvements are needed. I would be happy
to update the PR accordingly.

Thank you for your time and for maintaining this project.

Hi @hishamco , Thank you for the feedback. I had updated the README to explicitly mention creating the SimplCommerce database and how to adjust the connection string for different needs. Hopefully, this makes the setup process much clearer for new users!

Seems formatting JSON is annoying, @JayanthT7, please add the closing ``` for the JSON, then I will merge

Added the ending quotes for json.

Hi @hishamco , I've verified the raw Markdown to ensure all code blocks are properly terminated. The preview and the file diff now show the blocks are correctly fenced. Verified in preview of github as shown in attached image. Please let me know the exact space or line to be fixed if found breaking.
