stabilize tryRemoveChild()

[pahud]

This method was introduced in 2020 from this PR and aws-cdk-lib has some adoption. As it's still marked as experimental, we've seen customers having concern about that in production but we don't seem to have other methods to remove a child from a Node.

constructs/src/construct.ts

Lines 369 to 379 in 80aa122

	/**
	* Remove the child with the given name, if present.
	*
	* @returns Whether a child with the given name was deleted.
	* @experimental
	*/
	public tryRemoveChild(childName: string): boolean {
	if (!(childName in this._children)) { return false; }
	delete this._children[childName];
	return true;
	}

Please stabilize this method and remove the @experimental tag.
