Merge bitcoin/bitcoin#30597: doc: Drop no longer needed workaround for WSL

16d8261 doc: Drop no longer needed workaround for WSL (Hennadii Stepanov)

Pull request description:

  This PR effectively reverts commit 4f890ba from bitcoin/bitcoin#11437, which fixed some build issues on WSL seven years ago.

  Testing the current master branch @ 31a3ff5 on Windows 11 + WSL using Ubuntu 24.04 or Debian images, I noticed that the workaround is no longer required. Moreover, it doesn't affect the build process at all, which means the hashes of the built packages in depends remain the same and the `configure` log in the main build system remains the same as well.
