Clarify wording for MaxPhysicalHeight Quest when asked for below a bridge

[kmpoppe]

Use case
As per parent issue, the only thing giving users the hint that SC is asking for the physical height below a brdige is the little ruler to the right of the icon, the quest text reads exactly the same as when the maximum height was asked for reading a sign.

Together with the fact, that the physical quest is asked even when maxheight:signed=no (which is a valid answer for the MaxHeight quest), this leads to the confusing scenarion of users being asked the quest twice.

Proposed Solution
Update wording to "What is the physical height measured below this bridge?" or similar.

the quest text reads exactly the same as when the maximum height was asked for reading a sign.

Nitpick - I don't think the string isn't "exactly the same", but it is confusingly similar:

StreetComplete/app/src/androidMain/res/values/strings.xml

Lines 1192 to 1194 in 2d0e911

	<string name="quest_maxheight_title">"What’s the height limit here?"</string>
	<string name="quest_maxheight_below_bridge_title">What’s the height limit below the bridge?</string>
	<string name="quest_maxheight_sign_title">"What height limit is indicated here?"</string>

I agree that it can be confusing, and that we should clarify that the first two (used by AddMaxPhysicalHeight.kt) require physical measurement, and the last one is about a displayed street sign.

Together with the fact, that the physical quest is asked even when maxheight:signed=no (which is a valid answer for the MaxHeight quest),

IMHO it is not "even when"; it is intentionally "exactly when" -- i.e. it is a followup quest: "since height is not signed; could you please measure it instead?"

@kmpoppe Are you interested in making and testing PR? This change seems to make sense at least to me.

I guess part of question is whether retranslation should be forced by using new string code
