hid: bpf: Fix grammar
* spelling fix: XBox -> Xbox, lowercase 'b' as per Microsoft branding * rephrase: paddle -> paddles, the controller itself has more than one paddle * rephrase: replace usage of "those" in favor of explicitly making reference to the paddles * grammatical fix: report -> reports, use present tense verb. * spelling fix: interpret * consistency: capitalize the first word in bullet points Signed-off-by: Luis Felipe Hernandez <luis.hernandez093@gmail.com> Link: https://patch.msgid.link/20240625105553.50830-1-luis.hernandez093@gmail.com [bentiss: renamed the file into Xbox, not XBox] Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>
