Allow more prefixes for Autolink references

[BickelLukas]

I need to create a Autolink reference with the prefix cons. (e.g. cons.7259)

I get the following error message when trying to save: Reference prefix must only contain letters, numbers, or -:/#

Please allow . in the reference prefix

@BickelLukas we recently addressed the issue: https://github.blog/changelog/2021-11-04-more-flexible-autolinks/

Does this fix the problem for you?
