CodeFix: Remove relative path prefix from types loading

[asilverman]

Description

The current implementation makes the wrong assumption that the key names indexed in the types cache have a prefix ./. This was the case when I was using a dev artifact since the publishing logic wasn't ready.

Now that we have a publishing logic for the types package we can fix the code so that it doesn't assume the ./ prefix is found in the files as proven by https://github.com/Azure/bicep-types-az/actions/runs/6398352791/job/17368317634.

This PR should be merged before Azure/bicep-types-az#1553, and Azure/bicep-types-az#1553 should be updated to download the latest build from the main branch.
