1690994 - Document WSL2 workaround

Status: NEW

(Tree Management :: Treeherder, defect)

Description

[Ionuț Goldan [:igoldan]]

The docs for setting up the Treeherder' s docker environment on Windows aren't up to date anymore.

For more than half a year now, docker on Windows switched from WSL to WSL2, by default.
But our docker setup isn't yet able to run on WSL2.

A temporary workaround is to simply go into docker' s config (Docker Desktop.exe, that is) & manually switch it back to WSL:
click the gear icon >> General >> uncheck Use the WSL2 based engine.

Update the docs by including this workaround in them.
