Case-sensitive filename collision in `_events` breaks checkout on macOS

[IvoLeist]

Hi usegalaxy-eu team,

I tried to clone this repo with my macOS, so I can add myself to the team webpage :)
However I faced a path collision warning for two files inside the _events folder.

Summary

The repository appears to contain two files whose paths differ only by capitalisation

_events/2022-07-05-Community-Call.md
_events/2022-07-05-community-call.md

This causes a checkout warning and an unclean working tree on case-insensitive filesystems (default for macOS)

Reproduction

On macOS with a default case-insensitive filesystem:

git clone git@github.com:usegalaxy-eu/website.git
cd website
git status
git ls-files | grep -i '_events/2022-07-05-community-call.md'
ls -la _events | grep -i '2022-07-05.*community.*call'

Observed behavior

Git clone returns:

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:

  '_events/2022-07-05-Community-Call.md'
  '_events/2022-07-05-community-call.md'

After cloning, git status shows a modified file even though no changes were made:

On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  modified:   _events/2022-07-05-Community-Call.md

Expected behavior

The repository should be cloneable with macOS without any warnings about path collisions.

Suggested fix

Remove one of the colliding files
_events/2022-07-05-Community-Call.md
or
_events/2022-07-05-community-call.md

Environment

• OS: macOS
• Filesystem: default APFS, case-insensitive
• Branch: master
