Issue with trying to enable linear advance

[lofty147]

Hi, thanks for writing this guide

I am trying to enable linear advance with this updated marlin firmware. I end up with an error during compiling:

Marlin\src\inc\SanityCheck.h: "static assertion failed: It is strongly recommended to set DEFAULT_EJERK >= 10 when using LIN_ADVANCE. Enable ALLOW_LOW_EJERK to bypass this alert (e.g., for direct drive)."

It seems this was added to the sanity check file in v1.5 of linear advance in Marlin. I wasn't able to find the DEFAULT_EJERK or ALLOW_LOW_EJERK settings in configuration.h or configuration_adv.h. I didn't think it was wise to go digging depper for the setting.

Do you know if there is any fix for this, or any way I could enable linear advance?

Thanks a lot
