One happy person created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1795



## Description of problem:
Hello developers,
I successfully parsed a CRL file with an inner algorithm identifier of 1.2.840.98445.1.1.11 using GnuTLS, although GnuTLS did not display the specific information of the inner algorithm identifier in the parsing results. When Go parsed this CRL file, it displayed the error: "inner and outer signature algorithm identifiers don't match".

## Version of gnutls used:
GnuTLS 3.8.9

## Distributor of gnutls (e.g., Ubuntu, Fedora, RHEL)
Ubuntu

## How reproducible:
certtool --crl-info --inder --infile crl_wrong_inner_signature_oid.der

## Actual results:
[crl_wrong_inner_signature_oid.der](/uploads/28ee3b442af58491839a61c5dd69f71a/crl_wrong_inner_signature_oid.der)

## Expected results:
