Add examples for copying captures and videos

[ribosomerocker]

Description

Added two examples to the capture and record commands, my editor also stripped some spaces after the lines automatically, and I made tables more consistent.

Motivation and Context

It was added to ease beginners into using this, and to show how to use the save subcommand's "-" option in conjunction with xclip.

How Has This Been Tested?

using cargo test goes fine, but using cargo test --features test-ws produces two errors:

test x11::window::tests::test_x11_window ... FAILED
test x11::tests::test_x11_system ... FAILED

I haven't exactly changed anything in the other code, so I'm not sure

After running those two commands:

cargo fmt --all -- --check --verbose
cargo clippy --verbose -- -D warnings

Everything seems to work except for one thing:

I'm not really sure about this, neither
