Now with 100% more `pmbootstrap log`!

Created by: antonok-edm

Opening pmbootstrap log defaults to printing 30 lines of text, which almost always manages to contain the "^^^^^^^^" line while cutting off the actual error. Increasing the initial log output should make it easier to assist newcomers who are told to post their log for help, as well as making it slightly more convenient for experienced developers who don't keep the log open.
