Add Float ApplicationCommandOptionType

[DjDeveloperr]

Description

Add FLOAT Application Command Option type.

Why This is Needed

Just like there is INTEGER (4) Option type, we need Float.
Example use case would be convert currency, slow mode command like /slowmode time: 1.5 unit: minute, and maybe some math.
Definitely more use cases out there.

Alternatives Considered

Use String option type and parse & validate it on our side.

Additional Details

Nothing really.
