feat: Info message when LSP is out of date

Adds a custom key to the package.json indicating the latest version of forc-lsp at the time of the plugin's release. If the user's version of forc-lsp is older than that, they will see an info message.

@JoshuaBatty What do you think about this? I remember you had some objections.

I'm just worried there might be a situation where users are on a stable mainnet version of forc-lsp that might be behind the latest bleeding edge release. In this instance they might get this message shown to them every session which might be annoying.

That's a fair concern. We would have control over it though, as we manually set the minimum version to not receive the warning in the latestForcVersion field in package.json. So, we could set it only update it to the latest mainnet version.

Cool, makes sense. I'm happy for this to merge then.
