Avoid the use of 'you' in the documentation

[bcr]

Summary

Rewrite some sentences that contain 'you', which should be avoided according to the Be Clear subsection in the FDP Primer. In effect, the resulting sentences are easier to understand and often shorter.
I did not change programlistings and other output as these are from programs, which need to be changed first (out of scope of this change).

Test Plan

1. Apply the patch
2. Review the output
