Brief Description
-----------------
remove the check to derive the renewal value of elastic certs in show-certs.sh scirpt

Severity
------
Minor - this is a minor inconsistency, but is causing user confusion

Steps to Reproduce
-------------------
Elastic certs are managed by cert-manager by default, so we can remove the condition in the show-certs script where it compares the values of mon-elastic-services-extca-crt and mon-elastic-services-ca-crt secret to derive the values of renewal

Expected Behavior
----------------

    Remove renewal check for WRA certificates

    In show-certs script to derive the renewal field for WRA certs
    mon-elastic-services-secrets/ca.crt and
    mon-elastic-services-secrets/ext-ca.crt, the contents are
    compared with mon-elastic-services-ca-crt and
    mon-elastic-services-extca-crt secrets respectively, this is
    creating a confusion to the user from the show-certs script
    output when WRA fails to update the certificates as per its
    certificate management and also WRA certificates are managed by
    cert-manager by default, so removing this condition and keeping
    only secret exist check makes it clear for the user what is
    expected from the script output.

    TestCases:
    PASS: Have different contents in mon-elastic-services-secrets/
          ca.crt and mon-elastic-services-ca-crt and notice the
          renewal field for mon-elastic-services-secrets/ca.crt
          shows as "Automatic"
    PASS: Have different contents in mon-elastic-services-secrets/
          ext-ca.crt and mon-elastic-services-ext-ca-crt and notice the
          renewal field for mon-elastic-services-secrets/ext-ca.crt
          shows as "Automatic"
