Update vscode-languageclient to 7.0.0

Tested on my machine, this could fix haskell/haskell-language-server#2068.

nice, good catch, only a bit worried in case users has not upgrade their editors (for whatever reason)
is this the lastest one? did you have to upgrade your client?

The version 1.52.0 is from the lsp extension guide (https://code.visualstudio.com/api/language-extensions/language-server-extension-guide), and it's the latest version. Maybe an older vscode can work, which at least should include the support of semantic tokens. I don't know what the exact bound is, but imho people should always keep their editors up-to-date.

By specifying engines.vscode: "^1.52.0", the extension won't be loaded if a user's vscode version is older than that.
