Update all references to Raspberry Pi Press Books

[aallan]

So with the integration of new toolchain functionality, see:

• Integration of Raspberry Pi Press book titles #3035
• Custom template for integrating book links #3040

for details of that. There are three or four (or more?) instances where I've manually referenced Raspberry Pi Press books. These need ripping out and the new macro functionality used.

Should I also update references to datasheets like these or just books?

https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf
https://datasheets.raspberrypi.com/pico/raspberry-pi-pico-c-sdk.pdf

[aallan]

Those aren't "books" they're part of the documentation. So won't work with the macro.

[aallan]

It's stuff like https://www.raspberrypi.com/documentation/microcontrollers/micropython.html#where-can-i-find-documentation where we reference a Pi Press book that you're looking for.

Or https://www.raspberrypi.com/documentation/computers/os.html#going-further

[jehlers42]

Perfect, already captured those so expect a PR soon.

#3070 closes this issue.
