Modify ghcide requirements of hls-change-type-signature-plugin

[July541]

Reference #2884, I think hls-change-type-signature-plugin should also require ghcide >=1.7 since it uses printOutputable.

haskell-language-server/plugins/hls-change-type-signature-plugin/src/Ide/Plugin/ChangeTypeSignature.hs

Lines 134 to 138 in 6d319ba

	-- | Pretty Print the Type Signature (to validate GHC Error Message)
	sigToText :: Sig GhcPs -> Maybe Text
	sigToText = \case
	ts@TypeSig {} -> Just $ stripSignature $ printOutputable ts
	_ -> Nothing
