Update doesn't respect default value of locale_dirs from `-c` passed `conf.py`

[liborjelinek]

If conf.py doesn't explicitly set locale_dirs, it's ["locales"].

When I pass such conf.py to sphinx-intl update command, it incorrectly puts .po files to <cwd>/locales/<lang>/LC_MESSAGES/ (under currently working directory).

But the paths of locale_dirs are relative to conf.py, i.e. it should puts .po files to <conf.py dir>/locales/<lang>/LC_MESSAGES/ instead.

For this buggy behavior, you need to explicitly set locale_dirs = ["locales/"] in your conf.py, i.e., to its default value.

Thanks for your reporting.

I did a quick survey.
When the locale_dirs setting is not explicitly defined in conf.py, sphinx-intl update command outputs .po files to the current working directory (e.g., <cwd>/locales/<lang>/LC_MESSAGES/) instead of the expected path relative to the location of conf.py.

	ctx.locale_dir = None
	if ctx.config:
	cfg = read_config(ctx.config, tag)
	if "locale_dirs" in cfg:
	ctx.locale_dir = os.path.join(
	os.path.dirname(ctx.config), cfg["locale_dirs"][0]
	)

To fix this issue, ensure that locale_dir is always resolved relative to the conf.py location, even when locale_dirs is not set in conf.py.
