Regarding your question; I think there are many reasons why the high school setting is so popular in yuri manga.
First of all it might have all started with Maria-sama ga miteru. That's kinda like the godfather of modern yuri stories. ^^
The real focus on the high school setting started after that, I think.
2) In Japan showing interest in the same gender is a kids and teenage thing. That's what a lot of people believe. So for young girls to show interest in each other and have first love experiences with each other is a natural thing and it can be considered practice for a „real“ relationship later (with a man, of course) ^^
This leads to two things:
a) Sad yuri stories that end with the couple breaking up at the end of high school that we all love so much ;) And in general a lot of school focused stories.
b) It also gave authors an excuse to depict yuri more easily. Because in that stage of life it's all natural. Nothing wrong with showing that. That helped a lot, I'm sure, when yuri didn't have a lot of support in the industry. Because like that you could still get away with it.
3) In recent years, and talking about more than a decade now, the vast majority of manga and anime focuses on kids and teenagers... That's become the ultimate thing unfortunately...
Just take a look around and try to count the mainstream stories that focus on adults... Having a hard time finding any...? Good. Then welcome to the club! ^^
If you take a look at the 90s and before that; there were far more (not only, of course, but faaaar more) stories with adults than nowadays... I really miss those times... Stuff like Ghost in the Shell, Cowboy Bebop, Devil Lady, Hellsing, Harlock, Perfect Blue, Jin-Roh, Bubblegum Crisis, AD Police, Gunsmith Cats, Berserk, Armitage, Appleseed... like a lot of popular things focused on adults.
Try to make a list past 2005... I'm pretty sure it'll become really short.
So that's a general problem, not just with yuri.
I hope that it's slowly starting to change again... But I'm not really convinced yet...
4) The majority of people reading manga are kids, young adults and perverts with a general and unhealthy interest in everything “young” (just like Hollywood) ^^
And maybe 5) as well:
High School is a time of freedom, fun and choice! That's where it all starts. You still have the whole world to conquer! ;)
And even for everyone past that age it's still a nice stage to think back to... There's a lot of nostalgia coming along with it...
