Update Bambu Lab X1 Carbon 0.4 nozzle.json

[hogum]

Reduce material leakage and support high-temperature consumables

如果为了安全，还可以添加一个判断，不过很多人都抱怨pla使用250度冲刷带来的气味较大
{if nozzle_temperature_range_high > 250}
M109 S[nozzle_temperature_range_high] ;set nozzle to common flush temp
{else}
M109 S250 ;set nozzle to common flush temp
{endif}

@hogum Please align the indentation of the code. The change from "M109 S250" to "M109 S[nozzle_temperature_range_high" may be not safe. For example, the current temperature of the printing material is relatively low, while the temperature of the material left in the nozzle is relatively high. You change it into max(250, nozzle_temperature_range_high)
