When setting structured config values using `--path`, we automatically
treat values that can be converted into an integer via `strconv.Atoi` as
an integer, rather than as a string.
However, this ends up converting values like "0123456" into the integer
123456, stripping the leading 0, which isn't desirable for values like
commit SHAs, etc., where you want to keep the 0 (and keep it a string).
This change makes it so that values starting with 0 are not implicitly
converted to an integer; instead such values will remain a string.
