Updating issue templates again for rustbot

It turns out that our current issue template can sometimes trigger a rustbot error message, as can be seen in [#7626](#7626). I originally tested this in #7599, but it's apparently a bit inconsistent. This PR adds backticks to the commands, as correctly suggested by `@mikerite` in the comments. (Thank you!)

``@rustbot` label +S-blocked`

Now I also pushed a tiny link fix as well. 🙃
