Allow more filtering of openid claims and user properties

[rowleya]

The plugin allows filtering by email domain, which is useful, but my OpenID provider (Entra in this case) also provides some other things to filter on, which I think make it more secure (tenant-id in this case). To avoid this plugin being specific to a use case, I thought it was more useful to simply enable a regular expression on any token. This works in my testing for my case. The plugin config is simply updated with extra properties that start with regexFilter. e.g. for tenant-id in Entra, which is tid if I want to add this to filter to the manchester.ac.uk, nhs.net and icr.ac.uk tenants on the auth0 client, I can add:
openid.auth0.regexFilter.tid=37c354b2-85b0-47f5-b222-07b48d774ee3|c152cb07-614e-4abb-818a-f035cfa91a77|6138f7b9-eeea-47f7-a06b-b90a692f238e

This could also potentially remove the need for email domain filtering, since that could be simply done with:
openid.auth0.regexFilter.email=*\.manchester.ac.uk|*\.nhs.net|*\.icr.ac.uk

However as I suspect that use case is more common, it may be worth keeping that option too.

(I also updated some gradle things here as they weren't working for me - feel free to tell me you don't want those though and I can revert those changes)
