Subject: [PATCH] Adding custom move feedrate for G26 Travel moves, Original
 #20729 (#20879)

* Adding custom move feedrate for G26

This commit adds an additional configuration parameter that can be used to specify the movement speed during the G26 validation pattern command during moves without extrusion.

Closes MarlinFirmware/Marlin#20615
