[jetbrains-plugin] Update Workspace Timeout Logic

[Siddhant-K-code]

Description

This conversation started here. Also see this Internal discussion that the following logic is does not anymore:

gitpod/components/ide/jetbrains/backend-plugin/src/main/kotlin/io/gitpod/jetbrains/remote/actions/ExtendWorkspaceTimeoutAction.kt

Lines 33 to 39 in 478a75e

	if (result.resetTimeoutOnWorkspaces.isNotEmpty()) {
	message = "Workspace timeout has been extended to three hours. This reset the workspace timeout for other workspaces."
	notificationType = NotificationType.WARNING
	} else {
	message = "Workspace timeout has been extended to three hours."
	notificationType = NotificationType.INFORMATION
	}

And, This reset the workspace timeout for other workspaces. is not true. & It is also weird that it returns the current workspace in reset list:

gitpod/components/server/ee/src/workspace/gitpod-server-impl.ts

Lines 387 to 407 in 81e0623

	const workspace = await this.internalGetWorkspace(workspaceId, this.workspaceDb.trace(ctx));
	const runningInstances = await this.workspaceDb.trace(ctx).findRegularRunningInstances(user.id);
	const runningInstance = runningInstances.find((i) => i.workspaceId === workspaceId);
	if (!runningInstance) {
	throw new ResponseError(ErrorCodes.NOT_FOUND, "Can only set keep-alive for running workspaces");
	}
	await this.guardAccess({ kind: "workspaceInstance", subject: runningInstance, workspace: workspace }, "update");
	const client = await this.workspaceManagerClientProvider.get(
	runningInstance.region,
	this.config.installationShortname,
	);
	const req = new SetTimeoutRequest();
	req.setId(runningInstance.id);
	req.setDuration(validatedDuration);
	await client.setTimeout(ctx, req);
	return {
	resetTimeoutOnWorkspaces: [workspace.id],
	};
