Don't suggest bundle name as possible replacement for symbol links

[d-ronnqvist]

Bug/issue #, if applicable: rdar://125964139

Summary

This fixes a confusing diagnostic solution when a misspelled link matches the also misspelled bundle name (specified in an Info.plist)

Dependencies

None

Testing

In a any project with some module documentation:

• Add a documentation catalog with an Info.plist file that specifies a misspelled version of the module name for "CFBundleDisplayName".
• In any content, for example a documentation comment or an article, write a symbol link using the misspelled version of the module name.
• Build documentation for the project.
  • The diagnostic about the unresolved link should only suggest to replace the misspelled name with the correctly spelled module name.

Checklist

Make sure you check off the following items. If they cannot be completed, provide a reason.

• Added tests
• Ran the ./bin/test script and it succeeded
• ~ Updated documentation if necessary~ Not applicable
