tweak(environment): clean up .env-e files on macOS

[jaskfla]

Changes

When using sed with the -i flag to edit a file in place, macOS generates backups of the original file. These aren’t harmful but we don’t really want or need them.

There were a few alternative ways to get around this:

• print the file contents into a new file, and then use mv and rm to replace the old file
• use command substitution to cat the old file into a variable, run the find and replace, then echo it into the original file with >

I think those harm readability more than it’s worth; and it has to be done every in every place we use sed -i.
