targets: Add Shrike Lite board

[YajTPG]

Hello,

Pinouts: https://vicharak-in.github.io/shrike/shrike_pinouts.html

Also a quick question, while adding documentation for the board can I link users outside the tinygo-org repos or is it preferred to add the code to the doc itself?
I wanted to add the process of flashing the FPGA to the doc: https://github.com/YajTPG/shrike_go/blob/master/shrikeflash.go

Thanks!

I finally got around to check why the CI was failing, even after replicating the setup on my personal machine (same docker image, same commands used, etc) I couldn't get the test to fail, can you trigger a re-run please?

@YajTPG looks like a pretty interesting board. Thanks for working on adding it.

while adding documentation for the board can I link users outside the tinygo-org repos or is it preferred to add the code to the doc itself?

I personally like "getting started" level info in the tinygo docs, that link to the outside for more comprehensive info. So both? 😸
