Revert "feat(deploy): copy local git config to tmp repo (facebook#7702)"

This reverts commit ee376d1.

All git config fields can be set via the GIT_CONFIG_KEY_<n> and GIT_CONFIG_VALUE_<n> env vars.

Ref: https://git-scm.com/docs/git-config#Documentation/git-config.txt-GITCONFIGCOUNT

Alternatively, you can also use the conditional includes feature of git config.
