CI: Change APT mirror priorities (#39190)
We noticed many times that bootstrap sometimes takes a lot of time due
to slow download speed: [#general > Bootstrap is slow in CI @
💬](https://servo.zulipchat.com/#narrow/channel/263398-general/topic/Bootstrap.20is.20slow.20in.20CI/near/537610373).
We [reported this to
github](https://github.com/actions/runner-images/issues/12949) and they
said we should just use different mirrors. Based on
https://github.com/CrowdStrike/glide-core/pull/1113 we change Ubuntu's
mirror priorities from:
```
http://azure.archive.ubuntu.com/ubuntu priority:0
https://archive.ubuntu.com/ubuntu priority:1
https://security.ubuntu.com/ubuntu priority:2
```
to:
```
https://archive.ubuntu.com/ubuntu priority:0
http://azure.archive.ubuntu.com/ubuntu priority:1
https://security.ubuntu.com/ubuntu priority:2
```
I also set more strict timeout (10 min; usually it takes 2-3 min but
always less then 4 min) for bootstrap to alert us on problems.
