Prior to this commit, Actuator would sanitize properties values when
serializing them on the dedicated endpoint. Keys like "password" or
"secret" are entirely sanitized, but other keys like "uri" or "address"
are considered as URI types and only the password part of the user info
is sanitized.

This commit fixes the sanitization process where lists of such URI types
would not match the first entries of the list since they're starting
with `'['`. This commit improves the regexp matching process to sanitize
all URIs within a collection.

The documentation is also updated to better underline the processing
difference between complete sanitization and selective sanitization for
URIs.

  Polish 'Remove ResourceUtils.getURL logging config check'
  Remove ResourceUtils.getURL logging config check

Closes gh-22946

Extend `initializeSystem` to search the exception stack for a
FileNotFoundException before reporting the error. This allows
us to provide a similar stack trace to the one that used to be
thrown when we had the `ResourceUtils.getURL` check.

See gh-22946

Remove `ResourceUtils.getURL` checking from `LoggingApplicationListener`
so that logging systems can implement custom location support.

Prior to this commit, we checked in the listener if the specified config
location could be opened as a URL. This unfortunately prevents Log4J
extensions such as `log4j-spring-cloud-config-client` from implementing
configurable SSL and credentials support.
