[Handbook] Clarify when the user needs to reboot the system

[carlavilla]

Summary

This patch tries to help the users how to know if they need to reboot or not after an update of the system with the freebsd-update utility.

If you check the updating section in our Handbook freebsd-update you can see that says:

"If the update applies any kernel patches, the system will need a reboot in order to boot into the patched kernel."

With this patch I tried to solve this question.

@emaste you know if that note it's enought? I don't know if there's another easy way to check that.

Test Plan

Compile the handbook.

A few things that I've found. In general, I like the note and what it conveys.

We generally avoid the use of "you" in the handbook or other docs.
See section 14.1.1 of the FDP.

No sentence stop here, it's one long sentence (which is fine, I think).

s/if differs/if it differs/

Thanks for the advices. There's the new diff.

[bcr]

Two more things, we're getting there.

s/need/needs/

These are still two sentences. Remove the sentence stop here and put a comma there instead to connect it to the "execute the commands ..." sentence.

[carlavilla]

Done! Thanks.

[bcr]

Good to go.
