Removes some noise from the bug report issue template so people who
aren't familiar can submit issues with less friction. Some of these
might be a bit subjective, feel free to call out any nitpicky parts, I
didn't want to rewrite entirely. Mostly fixed typos & language issues,
other than that:
* Just "detailed information", no need to say "descriptive", and changed
"reproducible code and detailed information" to "or detailed
information" because code is good enough
* Simplified description label, mention code example can go there
* Changed "Possible Solution" to "Known Workarounds" because it's what
issue authors are more likely to know (and usually write anyway) and is
more useful to most readers.
* Doc link for "rebuilding the compiler" was broken, replaced it with
mentioning choosenim, nightlies and building a temp compiler which is
hopefully less offputting

Just to complain: Github issue forms have some problems themselves,
there's no option to disable the "No response" text when an optional
area is unfilled, and the textboxes are really small at least on Firefox
(though you can expand them). The alternative, issue templates, isn't
much better. Github also hides the ability to open a blank issue in a
text link in a small line after all the issue form buttons, I'm guessing
this is intentional for repositories which don't want blank issues but
we don't have such a problem. Worst comes to worst we can add a button
for a minimal/empty issue template.
