juju 3.2.2 contains pebble with a regression

[John A Meinel]

Pebble made a recent change to inherit env variables from the Pebble process to the services that it spawns. However it had an issue with HOME an USR
https://github.com/canonical/pebble/issues/260
https://github.com/canonical/pebble/issues/263

This was fixed by:
https://github.com/canonical/pebble/pull/262

However, 3.2.2 shipped with this pebble:
31: github.com/canonical/pebble v0.0.0-20230711093550-00bcd1f7dda5

but the fix landed as:
commit 02ad28a16a3594b38e242bfe0d7eef8a896db386

    Do not inherit HOME and USER env vars from pebble daemon environment (#262)

    Also use root home directory when running tests as sudo

Note that there are several other patches in pebble by this time, and there isn't a formal release process for pebble for us to select, but we can at least move to 02ad28.

Note that the Pebble "require" line in the go.mod on Juju's 3.2 branch already points at 02ad28, so there's nothing further to do here (other than ship 3.2.3).
