[JENKINS-47768] - Avoid having "authenticated" twice in the group membership of a user (LastGrantedAuthorities) (#3123)

* Avoid having "authenticated" twice in the group membership of a user
- this occur when the SecurityRealm potentially already grants that role (like in github-oauth-plugin)

* - changed as requested by Oleg
- the list has a maximum of roles.length and in reality it's either roles.length or (roles.length-1), so the maximum is ok

* - fix problem of missing the "authenticated" authority

* - convert the Groovy script to a Java version
- the Groovy test was not run by default (IIUC Groovy scripts are not compiled if placed in java src folder)

[JENKINS-47015] - Update Windows Slave Installer module to 1.9.2

[JENKINS-47909] @daniel-beck asks about usernames containing valid $ escapes. Behavior is partly broken.

- to ease the maintenance of plugins (avoid searching for first version providing it)

Correction French translation

It picks new release with one bugfix / performance improvement. Changelog: https://github.com/jenkinsci/windows-slave-installer-module/blob/master/CHANGELOG.md#192

Change one translation in French (in english: title was used instead of labels, misleading as for slaves it's labels)
