Rfc5424Layout "newLine" in XML configuration is no longer valid

[luisgoncalves]

Description

When upgrading from 2.22.0 to 2.25.3 I noticed the following in the status logger:

ERROR Rfc5424Layout contains an invalid element or attribute "newLine"

Configuration

Version: 2.22.0 -> 2.25.3

Reproduction

XML configuration file with <Rfc5424Layout newLine="true" ... />.

Seems to have been introduced by #2853. Using includeNL="true" fixes it, but the docs still mention newLine. I thought I'd share here because it also seemed a breaking change that I didn't find in the release notes.

@luisgoncalves, thank you for the heads up. We're aware of the issue and working on it.
