Update tinygo version recommendations

[lann]

We are still recommending 0.22, while the latest release is 0.26 which is broken. We should recommend 0.25.

the user reported 0.25 does not work either (in discord). i had tested it using v0.22.0 as suggested in docs, but i think i had heard success story with 0.24.0 as well

0.26 works for me (Manjaro Linux)

Original issue in the spin repo: spinframework/spin#820

0.26 works for me (Manjaro Linux)

Weird, I've checked on fresh Manjaro in VM, but it seems to fail for me:

tinygo version 0.26.0 linux/amd64 (using go version go1.19.2 and LLVM version 14.0.0)

Ah sorry, in discord I was looking at a compile error which doesn't happen in 0.26. The runtime error does reproduce. Thanks!
