gnu: mbedtls-apache: Update to 2.28.5.

This fixes mbedtls-apache failing some tests for unknown reasons after recent
updates and ungrafting to other packages.  This should soon be renamed to
mbedtls-apache-lts and a newer version added; see
<https://issues.guix.gnu.org/66718>.

* gnu/packages/tls.scm (mbedtls-apache): Update to 2.28.5.
