Describe the bug

When I added a numbers groups to the groups.yml like so:

`default:
tabprefix: "Default &a"
tagprefix: "Default &a"
1:
tabprefix: "Group 1"
tagprefix: "Group 1"
example_group:
header:
- "This is an example of per-group header/footer"
footer:
- "applied to a group"

default settings for all groups, all groups will take properties from this section unless player's primary group overrides a specific setting

DEFAULT:
tabprefix: "%luckperms-suffix% &7"
tagprefix: "%luckperms-suffix% &7"
customtabname: "%player%"

per-world:
world1:
Owner:
tabprefix: "&0&l[&a&lOwner&0&l] &a"
tagprefix: "&2&lOwner &a"`

Expected behavior

Be able to create numberd groups in the groups.yml

Steps to reproduce

Generate default files from scratch add a numbers group in groups.yml
1: tabprefix: "Group 1" tagprefix: "Group 1"

Plugin will break

Additional info

This used to work before but right now it does not work anymore might be some changes in the yml code

"2": tabprefix: "&0&l[&7&lPlayer&0&l] &3" tagprefix: "&2&lPlayer &3"
Adding the number between quotes will fix it!
