Clarify recommandation for table name

[MrYamous]

Hello

Currently, table name's conventions doesn't look clear to me (even if I'm used to PascalCase in my projects)

Documentation says camelCase is recommended, but example just above use PascalCase, and stubs generate name with kebab case

According to other common usages in PHP, PascalCase or camelCase looks good. WDYT ?

We can use camelCase; this can be done without any breaking changes.

Okay, I will work on PR for camelCase if it's good for you
