Search items

I would report some suggestions taken from https://github.com/chromiecraft/chromiecraft/discussions/7316#discussion-7105962

~We should list the items based on quality and alphabetically, but ideally we should put a feature to search the items~

~Edit: this issue is related to https://github.com/azerothcore/mod-transmog/issues/133~

We could add a search function

No file, test, or entry point is named. Start by reading the linked discussion and the related mod-transmog issue, then locate how transmog items are currently listed. Done means users can search the available items and the existing listing still behaves as expected.
