Ignore the URLs when checking if inferred links overlap existing LinkAnnotations (PR 19110 follow-up)

*Note:* For the issue mentioned on Matrix it'll obviously still make sense to improve the regular expression to detect more URL edge-cases.

However it occurred to me that even once that particular case is fixed there'll always be a risk that inferred links could overlap, and effectively block, the actual LinkAnnotations.
Hence this patch removes the URL comparison to ensure that overlapping inferred links will always be ignored.
