Use the store page on Seamus's fork of the condition markers extension

[SeamusFinlayson]

Make sure that your submission has the following:

• A link to the raw github markdown file with a YAML front matter definition containing:
  • The title of your extension
  • A description of your extension
  • The author
  • A hero image
  • An icon
  • Tags (these will help with your extension's discoverability)
  • A link to your extensions manifest

Please, go through these steps before you submit a PR.

• You have done your changes in a separate branch.

• You have a descriptive commit message with a short title (first line).

• You have only one commit (if not, squash them into one commit).

• Your pull request MUST target the main branch on this repository.

• Your pull request puts your extensions details as the last entry in the extensions.json file

Hi @SeamusFinlayson,

Thanks for taking on the maintenance of this one!

A couple of minor edits needed, please:

1. Could you replace the Discord invite link in your store.md with the 'official' one from our blog, YT channel etc: https://discord.gg/u5RYMkV98s
2. We're going to de-list Keegan's extension and add your fixed version once it has passed the usual verification, but hopefully it will be quicker than usual! If this means that you need to edit your entry in extensions.json (ie. submitting a new version rather than a swap-out substitute) then please do so!

Do you already have copies of the jpg files in https://raw.githubusercontent.com/kgbergman/conditionmarkers/main/docs/ just in case you will need to host them in future?

All the images and svgs are contained within the repo so that should be fine. I'll change the link and open a new pr.
