Chore: Is variant type 'number' supported?

[FredrikOseberg]

The variant type represents payload parsing hints for your application, but the value transmitted over the wire will always be a string. We will only perform validation, not actually parse the value for you. We need to update the documentation to be more clear in how Unleash deals with these scenarios.

Discussed in https://github.com/orgs/Unleash/discussions/6954

In the code such as here and in the UI such as in the screenshot below, the variant type 'number' seems to be supported.

However, in other code locations such as here and in the document here, there is no type 'number'.

Is it actually supported?
