[Documentation Update]: self assign the issues

[MohanRamSridhar]

Is there an existing issue for this?

• [X] I have searched the existing issues

Issue Description

there is only workflows that will comment on the issue

Suggested Change

I would like to create a workflow that will self assign the issue to a user if he or she wants the issue to be self assigned to them

Rationale

This will save time for both the suer and the PA and will also give the user time to start working on the issue

Urgency

Low
