Tool version check occurs too late

[hyangah]

The extension offers to update tools if the tools are too old.
Unfortunately, it occurs too late - after gopls starts. This doesn't play nicely with gopls's crashes.

vscode-go/extension/src/goMain.ts

Lines 123 to 126 in 40990c0

	await commands.startLanguageServer(ctx, goCtx)(RestartReason.ACTIVATION);
	suggestUpdates();
	offerToInstallLatestGoVersion(ctx);

Moreover, #3168 also kicks in, and prevents from compiling tools with the suitable go versions.

Hope that fixing #3168 helps this. We also have a new gopls release with the known crash causes fixed.
Since it requires non-trivial refactoring work, moving this to v0.42.0
