Persisting the data in Fly

When we update Actual, if we don't persist the data it will be erased each time we come to update.

Run the following command
```
flyctl volumes create actual_data --region lhr
```
This will create a volume in the london region. Replace lhr with another region code if desired.
You should then get a message to say it was successful
Open up fly.toml in notepad - you can do this from the command line
```
notepad fly.toml
```
Add the following to the file
```
[mounts]
    source="actual_data"
    destination="/data"
```
If you created a volume with a different name, put that in the source. Save the file.
Now from the command prompt run
```
flyctl deploy
```
Your application should be re-deployed with the updated configuration

If all went well, you should now be able to see your volume from the fly.io dashboard.
