chore: Improved the issue templates with issue forms (supported viayml ) (#612)

GitHub supports the issue forms [1].
[1] https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository#creating-issue-forms

This feature allows users to create issues using a structured and visually appealing form. This functionality is facilitated through a  file for the issue template.

Added the issue template for bug report, feature request, and improvement by adding respective  file. Also, removed previous  file which is no longer needed

.github/ISSUE_TEMPLATE/improvement.yml
