Issue Template Updates for Figma link

[thisiskaransgit]

Current Behavior

The project's current issue templates are missing an open invitation link where new contributors can join the community's Figma team and view user interface designs and other UX projects.

Desired Situation

Each template that has a reference to Figma in its resources section should an invite link added.

Implementation

- 🎨 Wireframes and [designs for Meshery UI](https://www.figma.com/file/SMP3zxOjZztdOLtgN4dS2W/Meshery-UI) in Figma [(open invite)](https://www.figma.com/team_invite/redeem/qJy1c95qirjgWQODApilR9)

Acceptance Tests All references to Figma include the "open invite" link.
