I18N: Use correct default value for JavaScript translations path.

The `$path` parameter of some script translation functions had a default value of `null`, even though the parameter is documented as a string.

This commit corrects the default value for `$path` in:
* `WP_Dependency::set_translations()`
* `WP_Scripts::set_translations()`
* `wp_set_script_translations()`

Additionally, this commit removes an `is_string()` check for `$path` in `load_script_textdomain()`. Now that the default value for `$path` in that function has also been corrected to an empty string instead of `null`, that check is no longer necessary, as it would ''hide'' an error which should be ''fixed'' (at the source of the problem) instead.

Follow-up to [54349].
