Link to report issues is broken

[shamlian]

The left sidebar item for reporting issues is malformed and leads to a broken link.

I believe the issue is a trailing underscore on this line (and perhaps also the back ticks):

IntroToRoboticsV2/index.rst

Line 139 in de57ddc

`Report course issues <https://github.com/Open-STEM/IntroToRoboticsV2/issues>`_

Anyway, I got here manually. Nice work otherwise!
