[MAINT] Bump version to 0.16.2dev0 (#2137)

This PR fixes an issue with the locator in the
`test_version_switcher_highlighting` test, which should allow #2133 to
pass automated tests.

Note that this test is not run by CI, but that should be addressed in
#2133. To test, please run this manually.

(Sorry about the extra PR - I don't have permissions to push to the
branch in #2133). cc @trallard
