Add service=shared_driveway as valid value

[moi@…]

Hi,

On https://josm.openstreetmap.de/browser/josm/trunk/resources/data/validator/deprecated.mapcss:
1132 /* #12771, #9895 */
1133 *[noexit][noexit!=yes][noexit!=no], /* noexit=no has an own warning */
1134 way[highway=service][service][service !~ /^{(alley|drive-through|drive_through|driveway|emergency_access|parking_aisle|rest_area|slipway|yes)$/], /* drive_through and yes have special warnings */
1135 way[railway=rail][service][service !~ /}(crossover|siding|spur|yard)$/],
1136 way[waterway=canal][service][service !~ /^{(irrigation|transportation|water_power)$/] {
1137 throwWarning: tr("The key {0} has an uncommon value.", "{1.key}");
1138 }}

=> It should be good to add shared_driveway as a valid service value. Since ​https://community.openstreetmap.org/t/is-there-a-reason-to-prefer-service-pipestem-over-service-driveway-driveway-pipestem-or-is-shared-driveway-a-driveway/138061, the usage of shared_driveway is increasing a lot: ​https://taginfo.openstreetmap.org/tags/service=shared_driveway.
Currently, it is seen as an invalid value.

Kind regards
