Proposal to migrate the GitHub Models endpoint from the deprecated Azure URL to the GitHub Rest API

[garman]

The models.inference.ai.azure.com URL for GItHub Models inference has recently been deprecated in favor of github.models.ai.

Could the url be changed in githubmodels.lua to https://models.github.ai/inference/chat/completions? I believe that would be the only change necessary to migrate to the new endpoint. There is a potential that the listed model names would need some tweaks to match the id field in the response from https://models.github.ai/catalog/models as described in https://docs.github.com/en/rest/models/catalog, but I don't believe thats necessary.

I'm not sure many people are using that adapter so thanks for spotting this! Feel free to put a PR together for this fix.

Sounds good! #1914 has been opened.
