(GH-129848) (#131350)
gh-129843: fix pure Python implementation of `warnings.warn_explicit`
(GH-129848)
The pure Python implementation of `warnings.warn_explicit` constructs a
`WarningMessage`
with an incorrect source (it incorrectly sets the WarningMessage's line to the
given `source`).
(cherry picked from commit 80e00ecc399db8aeaa9f3a1c87a2cfb34517d7be)
