Go To File Should be able to open relative/partial paths

### Description

it is common to copy paths from github source or similar. Finding those path quickly in my editor without modification makes for a more refined user interface. This functionality exists in VS code. I think we should look at bringing this over to netbeans.

From implementation point of view this should basically work similar to sql `LIKE '%%'`.

Its the small details that make the experience hard to leave

### Use case/motivation

After using VScode and seeing the small details that make it a good editor. I think netbeans can steal small details refinements like this and make using netbeans even better.

No

Start by locating NetBeans' existing Go To File action and its current path-matching behavior. Implement support for opening files from relative or partial paths, and verify that paths copied from sources such as GitHub resolve to the intended file.
