docs: add missing throw descriptions in JSDocs

[xDivisionByZerox]

Add missing and updated @throw descriptions in the JSDocs for the following functions:

Updated	Added
faker.number.int	faker.number.int
faker.number.float	faker.number.float
faker.number.binary	faker.number.binary
faker.number.octal	faker.number.octal
faker.number.hex	faker.number.hex
faker.number.bigInt
faker.datatype.number	faker.datatype.number
	faker.datatype.float

Additionally, to make sure that those statements are actually true, I adjusted or extended the test for those functions as well.

This is somewhat blocked by #2444

This is somewhat blocked by #2444

Should we add https://github.com/faker-js/faker/labels/s:%20on%20hold?

[ST-DDT]

The jsdocs get improved by this regardless, so I don't consider it worth hard blocking.
(It only looks slightly ugly in the api-docs)

This is no longer soft blocked by #2444.
