For those looking for a workaround without disturbing your env, I found a quick and easy way to do it.

Download a compatible version of go as described in official docs:

$ go get golang.org/dl/go1.13
$ go1.13 download

You can now use GOROOT=`go1.13 env GOROOT` tinygo. Set that as an alias for convenience.
