Can't build FSharp.Editor: duplicate "Show_Return_Type_Hints" in xlf files

[majocha]

Show_Return_Type_Hints id in translation files got somehow duplicated and VS complains when trying to build FSharp.Editor.

for example

fsharp/vsintegration/src/FSharp.UIResources/xlf/Strings.zh-Hans.xlf

Lines 110 to 119 in 0825e8c

	<trans-unit id="Show_Return_Type_Hints">
	<source>Display return type hints (preview)</source>
	<target state="translated">显示返回类型提示(预览)</target>
	<note />
	</trans-unit>
	<trans-unit id="Show_Return_Type_Hints">
	<source>Display return type hints (preview)</source>
	<target state="new">Display return type hints (preview)</target>
	<note />
	</trans-unit>

Should be fixed by #15033
