Currently default value of fingerprint_generator argument of PlaywrightCrawler.__init__ is None. Use DefaultFingerprintGenerator() instead.

Add helper method to FingerprintGenerator that will override some fingerprint generation settings of already initialized FingerprintGenerator and add something like "allow_init_overrides" flag to FingerprintGenerator.

FingerprintGenerator should then support something like this:

fg = FingerprintGenerator(some_args..., allow_init_overrides=True)
fg.override_init(some_args...) -> "Will override settings"

fg = FingerprintGenerator(some_args..., allow_init_overrides=False)
fg.override_init(some_args...) -> "Will raise an error"

PlaywrightCrawler will have DefaultFingerprintGenerator(allow_init_overrides=True) in init and then it can use some PlaywrightCrawler.__init__ args override FingerprintGenerator settings -> for example browsertype.

On the other hand user can forbid such overrides if they pass FingerprintGenerator(some_args..., allow_init_overrides=False)
