I tried the rendered version and saw that multiple references in a row look kind of confusing. Using the issue handles(e.g. #8642) as the label might look better.

Suggested change

	* Enhance Quasar types to be more precise, provide guidelines for community contributions ([reference](https://github.com/quasarframework/quasar/issues/8642) [reference](https://github.com/quasarframework/quasar/issues/8493) [reference](https://github.com/quasarframework/quasar/issues/11090) [reference](https://github.com/quasarframework/quasar/issues/11043))
	* Enhance Quasar types to be more precise, provide guidelines for community contributions (references: [#8642](https://github.com/quasarframework/quasar/issues/8642), [#8493](https://github.com/quasarframework/quasar/issues/8493), [#11090](https://github.com/quasarframework/quasar/issues/11090), [#11043](https://github.com/quasarframework/quasar/issues/11043))

Also, we can do the same for others even if there is a single reference, if applicable(_issues, PRs, and discussions). If it's on another repo like quasarframework/rfcs, then we can do quasarframework/rfcs#10. AFAIK, GitHub already handles these types of links in issue comments, descriptions, etc. but on Markdown files. So, we can try to replicate the behavior.
