Current kokkos submodule reference is not a tree

[ambrad]

The version of EKAT that SCREAM uses has a Kokkos submodule reference that is not a tree.

Github message: "This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository."

git CLI message:

fatal: reference is not a tree: b52f8c835f4df003954dad66d9761094f8baa66c
Unable to checkout 'b52f8c835f4df003954dad66d9761094f8baa66c' in submodule path 'externals/ekat/extern/kokkos'
Failed to recurse into submodule path 'externals/ekat'

Uhm, I did a fresh clone of ekat, checked out the sha used by SCREAM, and updated submodules, without an error. It is true that there is no branch associated to that commit, but there is a tag:

[kokkos ((HEAD detached at b52f8c835))]$ git log -1
commit b52f8c835f4df003954dad66d9761094f8baa66c (HEAD, tag: 3.6.00)

so git submodule update --recursive should be able to check out that commit, no?
