Build: increase timeout for downloading inkuire.js from GitHub

[griggt]

I have seen this timeout on more than one occasion in CI.

Maybe we actually need retry?

I assumed that 20s is enough for such small file but if CI fails then we should increase the limit.

I sporadically encounter the same timeout issue when building the many Scala 3 software distributions on my Windows laptop (with low speed home connection).
