mkdocs-bibtex does not render citations where a period (.) exists in the key

[NixImagery]

When rendering a site with mkdocs using the mkdocs-bibtex plugin, citations are not recognised if they have a period within the citation key.

I tried a minimum working example and could reproduce the behaviour. To reproduce the behaviour, set up a folder containing the files below and run the command mkdocs serve. The browser should render both citations correctly but it only functions as expected for the citation key without the period.

Site structure:

• MWE
  • docs
  • index.md
  • mkdocs.yml
  • mwe.bib

index.md

# Home

Blah blah [@Jarse2023]. 

Woof woof [@Jarse.2023]

}

Haven't forgotten this. Just haven't had time to really work on it. I'm trying to get the tests refactored so they are grouped by feature so i can keep track of what is breaking better.

Should be working with v2.8.13
