Failure while renaming Layout folder on Linux

[bancer]

I have done the steps derscribed in https://book.cakephp.org/4/en/appendices/4-0-upgrade-guide.html#use-the-upgrade-tool without upgrading cakephp to 4.x.

# Install the upgrade tool
git clone https://github.com/cakephp/upgrade
cd upgrade
git checkout 4.x
composer install --no-dev

bin/cake upgrade file_rename templates /path/to/project

Executing bin/cake upgrade file_rename templates /path/to/project --verbose exited with an exception:

When I looked inside /path/to/project/templates folder I saw "layout" folder in lowercase.

System: Ubuntu 20.04 LTS. PHP 8.3.6

By the way, unit tests fail on 4.x branch with a similar error:

git checkout 4.x

vendor/bin/phpunit ./tests/
