Use cli version instead of Coder version

[code-asher]

When connecting to the remote we use the Coder version to determine which flags are supported, but we should get the local cli version instead because it does not necessarily match (if the user has downloads disabled and is using an old cli).

Instead of all this:

vscode-coder/src/remote.ts

Lines 197 to 218 in b35779a

	const buildInfo = await workspaceRestClient.getBuildInfo()
	const parsedVersion = semver.parse(buildInfo.version)
	// Server versions before v0.14.1 don't support the vscodessh command!
	if (
	parsedVersion?.major === 0 &&
	parsedVersion?.minor <= 14 &&
	parsedVersion?.patch < 1 &&
	parsedVersion?.prerelease.length === 0
	) {
	await this.vscodeProposed.window.showErrorMessage(
	"Incompatible Server",
	{
	detail: "Your Coder server is too old to support the Coder extension! Please upgrade to v0.14.1 or newer.",
	modal: true,
	useCustom: true,
	},
	"Close Remote",
	)
	await this.closeRemote()
	return
	}
	const hasCoderLogs = supportsCoderAgentLogDirFlag(parsedVersion)

We could do something like supportsCoderAgentLogDirFlag(version(binPath)) where version comes from cliManager.ts, and make version return a SemVer.

Or it maybe makes sense to have a features(binPath) on cliManager that returns all the supported features of the CLI (this is how we do it in the JetBrains plugin). So it returns an object like { logDir: true }.
