fix deep link by proper tag extraction when slash is in tag

Description

I updated the swagger-ui-config.yaml with a snippet that changed pet/list into pet-list for the name and tag. Docs/samples/swagger-config.yaml.
I changed the url to "./openapi.yaml" for testing purposes but can still be changed to the initial url in comment in the file. Dist/swagger-initializer.js

Motivation and Context

This change was required to allow the extraction of the link after the forward slash.

Closed #5875
