Rollup merge of #119679 - compiler-errors:issue-templates, r=Mark-Simulacrum

Ask for rustc version in diagnostic reports, remind users to update their toolchain

IDK why we don't ask for rustc toolchain when filing diagnostic issues. Diagnostics are sometimes very dramatically affected by compiler version, and users may report old diagnostic issues that were fixed by subsequent rustc versions that they have yet to update to.

For example, #119678 was made a bit more difficult to triage due to the template not asking the issuer to report their rustc version.
