git.txt: fix synopsis of `--config-env` missing the equals sign

When executing `git -h`, then the `--config-env` documentation rightly
lists the option as requiring an equals between the option and its
argument: this is the only currently supported format. But the git(1)
manpage incorrectly lists the option as taking a space in between.

Fix the issue by adding the missing space.
