Update mdlint to disable descriptive-link-text (#7481)

Update the mdlint CI to ignore a newly introduced lint which is overly strict (IMO).

Example failure:

https://github.com/sigp/lighthouse/actions/runs/15102688734/job/42446029011?pr=7479


  Ignore the new lint that requires link text to be descriptive. IMO it is completely fine to write links like `See docs [here](http://url.com)`.
