Bug description

Sell/Buy signs should not be case sensitive.

Only tested with deepslate.

Steps to reproduce

If you can't reproduce it then there is nothing to fix.

Expected behaviour

The sign should not work regardless if the name of the item/block is lower or upper case or a mix of both.

Actual behaviour

The sign doesn't work. It's case sensitive.

I can't reproduce this on the following:

[18:55:44 INFO]: Server version: 1.17-R0.1-SNAPSHOT git-Paper-66 (MC: 1.17)
[18:55:44 INFO]: Brand version: Paper
[18:55:44 INFO]: EssentialsX version: 2.19.0-dev+177-9d3bf33
[18:55:44 INFO]: LuckPerms version: 5.3.48
[18:55:44 INFO]: Vault version: 1.7.3-b131

All of the below signs worked as intended

I wasn't able to use the same cobbled_deep alias as you though, seems like the closest thing is cobbled_deepslate but that doesn't fit on a sign (for me?). If you used the custom_items.yml file to create your cobbled_deep alias, then you would experience the behaviour you're seeing here. I'm not sure whether or not case sensitivity for custom item aliases is intended or not, but for now you can add or change the alias to fit your desired formatting.
