What happened?

Description

When i try to set for example the to email or bcc email in a commerce email. It just saves the string that my .env variable is set to in the .yaml instead of the actual variable name.

Steps to reproduce

1. Create an email in commerce.
2. Set the bcc to an .env variable (it does recognise it)
3. Check the project config or reload the page and the .env variable name will be replaced with the value.

Expected behaviour

Native craft .env variable use in the cms.

Actual behaviour

Not saving the variable name but the value so you cant set it to something else in different environments.
