[PATCH v6 6/6] config: make git_configset_get_string_tmp() private

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <dstolee@microsoft.com>

This method was created in f1de981e8 (config: fix leaks from
git_config_get_string_const(), 2020-08-14) but its only use was in the
repo_config_get_string_tmp() method, also declared in config.h and
implemented in config.c. Since this is otherwise unused and is a very
similar implementation to git_configset_get_value(), let's remove this
declaration.
