Add support for links in Steps component titles

The Steps component doesn't seem to support links yet.

Adding this support would increase the component's flexibility + be greatly appreciated!

Relatedly, I couldn't find the current Steps component source -- I do see this PR adding it to the docs #96 2023/09/05, with the actual components repo having a closed PR mintlify/components#89 by @KenzoBenzo 2023/09/04
