[Bug]: Fix grammar errors and wrong license link in README.md

[yahyatouil-dev]

Describe the issue

Two documentation bugs found in README.md:

1. Wrong license link in the introduction section points to the VSCode
   repository instead of BCApps:

   • Current: https://github.com/microsoft/vscode/blob/main/LICENSE.txt
   • Expected: https://github.com/microsoft/BCApps/blob/main/LICENSE

2. Grammar errors in the Repository Structure section:

   • "build folder contain" → "build folder contains"
   • "applications are build" → "applications are built"

Both fixes are in README.md only. A PR is ready to be submitted once this
issue is approved.

Expected behavior

1. The MIT license link should point to BCApps' own LICENSE file:
   https://github.com/microsoft/BCApps/blob/main/LICENSE

2. The Repository Structure section should read:

   • "build folder contains the magic around how the applications are built"

Steps to reproduce

1. Open README.md in the root of the repository
2. Look at the introduction section for the wrong license link
3. Look at the Repository Structure section for the grammar errors

Additional context

No response

I will provide a fix for a bug
