Fix for Keywords Field in @project-sunbird/common-form-elements-full

[rajnishdargan]

While using the npm package @project-sunbird/common-form-elements-full version ^8.0.0, I noticed that the keywords field was not displaying in the form.

Investigation and Solution:

• When I installed the package, I discovered that it required ngx-chips as a dependency. However, the package documentation did not specify which version of ngx-chips to use.
• Initially, I installed version 2.2.2 of ngx-chips, which resolved the errors and allowed the application to run. However, the keywords field still did not display.
• Upon upgrading ngx-chips to version 3.0.0, the keywords field began to display correctly.
• You can verify this issue and its resolution in this sample repository: https://github.com/rajnishdargan/test-sb-form.

Steps Taken:
To further analyze the issue, I set up the SunbirdEd-forms repository locally. During the process, I encountered some issues running the repo and made the following changes to make it functional:

Added ngx-chips as a peer dependency to resolve compatibility issues.
I have raised a Pull Request in the SunbirdEd-forms repository with these changes.

Request:
I kindly request the team to review the proposed changes in the PR. If everything looks good, please merge the changes and publish a new version of the package to ensure seamless integration for other users.
