docs: describe cloud environments in fingerprint denylist (#19952)

Browse Source 
This PR changes the example of the client config option "fingerprint.denylist"
to include all the cloud environment fingerprinters. Each one contains a
2 second HTTP timeout to a metadata endpoint that does not exist if you are not
in that particular cloud. When run in serial on startup, this results in
an 8 second wait where nothing useful is happening.

Closes #16727

will be disabled. A common use-case for the fingerprint denylist is to disable
fingerprinters of irrelevant cloud environments, which can slow down client
agent startup time.
