Typo in the help text for the "Show as expanded" option for menu items: hierarchial -> hierarchical

[klonos]

As per the issue title, there's a "c" missing there in the word "hierarchial".

OK, here's one that's not beyond my skills to check.

LGTM. WFM.

Thank you @bugfolder 🙏🏼

This typo was discovered while responding to a thread in Zulip, where it was pointed out that the help text itself may not be 100% clear the way that it is currently phrased.

Since we are already changing the translatable string in order to fix the typo, I would like to also propose to tweak the help text to do a better job at explaining things. If we want to be 100% accurate with the description, then I was thinking something like this:

Automatically expands this menu item if it contains any children items. This setting only applies when the block for the %menu_name menu has been configured to use the "hierarchical tree" style.

Perhaps that deserves a follow-up UX task though 🤔

Let's make it a follow-up, because I anticipate some discussion over the revised wording. (Bikeshedding, anyone? 😉) Let's take our victories as we get them, however small.

Chalk this one up as a victory. Thanks @klonos and @bugfolder -- merged into 1.x and 1.25.x.
