docs: add tau as runtime for tinygo wasm modules

[deadprogram]

@samyfodil I think this might be better as an addition to https://github.com/tinygo-org/awesome-tinygo what do you think?

[samyfodil]

@deadprogram Just like extism, tau runs wasm modules compiled with tinygo. it also uses tinygo as default wasm compiler for go. This is why I thought adding it here. I don't think it really fits in awesome-tinygo because tau itself can't be compiled with tinygo.

In that case, please keep the list in alpha order.

@deadprogram done :+1:

Thanks for the update @samyfodil now squash/merging.
