docs: rename ISSUE_TEMPLATE Directory

[officeneerajsaini]

Fixes Issue

Closes #1036

Changes proposed

Rename The issue template directory . ISSUES_TEMPLATE --> ISSUE_TEMPLATE .

Note to reviewers

I renamed this directory because its name was ISSUES_TEMPLATE, and the template files were not working. After changing the name of the directory to ISSUE_TEMPLATE, it should be working.
