docs: gpio: intro: Improve HTML formatting 



Currently the HTML output for Documentation/driver-api/gpio/intro.rst
doesn't look right. The lines that start with LOW or HIGH are formatted
in bold, while the next line after each is not bold.

With this patch, the HTML looks better.

support it, there's a common idiom you can use to emulate it with any GPIO pin

that can be used as either an input or an output:



 LOW:	gpiod_direction_output(gpio, 0) ... this drives the signal and overrides

	the pullup.

 **LOW**: ``gpiod_direction_output(gpio, 0)`` ... this drives the signal and

 overrides the pullup.



 HIGH:	gpiod_direction_input(gpio) ... this turns off the output, so the pullup

	(or some other device) controls the signal.

 **HIGH**: ``gpiod_direction_input(gpio)`` ... this turns off the output, so

 the pullup (or some other device) controls the signal.



The same logic can be applied to emulate open source signaling, by driving the

high signal and configuring the GPIO as input for low. This open drain/open
