* 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

* Fixing missing default 'G26_XY_FEEDRATE_MOVE' value

This commit adds a default 'G26_XY_FEEDRATE_MOVE' value (max movement speed / 1.5) in the G26.cpp - same behaviour as the default 'G26_XY_FEEDRATE' value

* Adding comment describing functionality in G26.cpp

* Renaming 'G26_XY_FEEDRATE_MOVE' to 'G26_XY_FEEDRATE_TRAVEL'

Configuration parameter renamed for better readability and consistency

MarlinFirmware/Marlin#20615

* Setting 'G26_XY_FEEDRATE_TRAVEL' to a safer value, aligned comments

Changed default value for 'G26_XY_FEEDRATE_TRAVEL' from 150 mm/s to 100 mm/s for safety purposes, comment alignment
