chore(deps): update tinygo version

[flavio]

Go policies: use latest version of tinygo to build the policy during the release process.

This will hopefully fix release errors like this one:

Run tinygo build -o policy.wasm -target=wasi -no-debug .
  tinygo build -o policy.wasm -target=wasi -no-debug .
  shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}
error: requires go version 1.18 through 1.19, got go1.20

The latest version of tinygo should be happy when go 1.20 is found

BTW, once this gets merged I guess I'll have to do the following actions:

• replace all the references of 3.1.1 with 3.1.2
• merge this change
• tag 3.1.2
• update the go policies that are currently broken to use the 3.1.2 release

Am I right?

Yes, that is correct.
