Improve english texts

[koebi]

When reviewing a foreign language PR, I noticed that the english texts lack in some places: https://github.com/GIScience/ors-map-client/blob/1ec61b7e7ec5e9b4d91715c3fe52b128b8ad425c/src/fragments/map-view/i18n/map-view.i18n.en-us.js#L46-L48

They are probably the basis for any translation, so I suggest the following improvements:

• Define polygons to avoid during route calculation
• Define rectangles to avoid during route calculation
• Polygons are not allowed to intersect.

I'm open for discussions whether "Define" or "Draw" is more appropriate here.

👍🏻 would vote for "Draw" instead of "Define"

Also note, that the translation file is named differently from the component.

couldNotDetermineYourLocation: 'Your location could not be determined. Make sure granted the required permissions',

noPlaceFound: 'No place found with the imputed content',

unknownSearchPlaceError: 'Unknown search place error'

better: location?
