Ambiguous identifier when notes share the same file name with different capitalisation

[zX3no]

Describe the bug

I have this file structure:

test/
┣ a/
┃ ┗ Note.md
┣ b/
┃ ┗ note.md
┗ root.md

When writing in root.md I'm trying to add the two notes a/Note.md and b/note.md. Using autocomplete after typing [[, I get an warning for an ambiguous identifier. Both notes complete like this: [[Note]] and [[note]].

Small Reproducible Example

Steps to Reproduce the Bug or Issue

1. Create two folders with a file that has the same file name with different capitalisation.
2. Create a note in the root.
3. Type [[ and try to autocomplete one of the notes.
4. It should say 'Resource identifier is ambiguous'.

Expected behavior

When files have the same capitalisation and the file structure is like this:

test/
┣ a/
┃ ┗ Note.md
┣ b/
┃ ┗ Note.md
┗ root.md

Autocompletion works correctly and detects the ambiguity. The notes are completed as [[a/Note]] and [[b/Note]].

Thanks for reporting this, yup looks like a bug.
Off the top of my head the issue is in FoamWorkspace.getShortestIdentifier, if someone wants to take a look maybe start from there.
