chore(gh): add link to SO MVCE in bug templates

[agilgur5]

Motivation

• further highlighting what minimal means, since we do get some reports that are far from minimal

  • and also some reports without a repro what-so-ever 😕
  • Recent examples: 3.4+ log propagation issue -- need larger fluentbit buffer size #13314, workflow status stuck in Running occasionally (no repro) #13238, outbound node of itself #13164, etc etc

• will this help?

  • a small bit maybe. higher quality reports do this already as do higher quality SO questions, but lower quality reports & questions still miss this and so this page still gets linked often
    • I figure we should at least try to educate lower quality reporters on how to do this
      • hence do this automatically in the issue template, over manually doing it in responses (which may still be necessary unfortunately, but hey then it's a quick copy+paste at least)
  • I also added a description mentioning use in prioritization, to hopefully incentivize the behavior as well (and a non-reproducible issue is effectively not prioritized what-so-ever, so this is accurate)

Modifications

• Add a link to SO's "minimal, reproducible" page (fka MVCE): https://stackoverflow.com/help/minimal-reproducible-example
• Add a description explaining that this is "essential" and necessary for "prioritization" to attempt to incentivize the behavior

Verification

It seems a shame you can't linkify in the label where it might get more attention, but at least we have an easy link to point people at now. I like the page you've linked to a lot.

Yea I link to it manually with some frequency. It has gotten a lot of iteration and effort on it since on SO it is very common to link to as well. The page might have existed for over a decade (idr)
