🪲[Bug]: not working on case sensitive filesystem

[mblaschke-daimlertruck]

Describe the bug

the module is called "JWT" (regardless of the case specified in Install-Module) but the psd1 and psm1 files have a different case (Jwt).

On systems with case sensitive filesystem this breaks the module loading.
