Attempt to fix scheduled public data export cron

This hasn't actually been running, and I'm finally looking into why!
I tested this by running `sudo -u impress COMMAND_GOES_HERE`, and found
that there were two errors: both the lack of `production.env` that I
had noticed and expected, but also that Ruby 3.3.0 wasn't in the `PATH`
value.

To fix this, I now pull in both `/etc/profile` and `~/.bash_profile`,
much like what happens automatically when we log into a shell as
`impress`, to get the environment set up! I haven't actually validated
that this Works, but I guess we'll see! I *could* change the cron
timing to some immediate time to try to watch it happen, but I'm not
invested enough right now, there's other things to do!
