[Bug]: puppetserver ca clean fails with date format concerns

Describe the Bug

I've got a puppet CA going back to 2015. When I attempt to clear a cert from one of the older machines, I see something like this:

[root@PUPPET-CA ~]# puppetserver ca clean --certname HOSTNAME                   
Error:
    When attempting to revoke certificate 'HOSTNAME', received:
      code: 500
      body: Internal Server Error: java.lang.IllegalArgumentException: Invalid format: "2020-11-29T17:07:23+00:00" is malformed at "+00:00"

This may have something to do with inventory.txt having multiple date formats included, because of the age of the system. Matching lines for that host in here:

0x0477 2015-11-30T17:07:23+00:00 2020-11-29T17:07:23+00:00 /CN=HOSTNAME         0x1D46 2017-07-25T20:24:26UTC 2022-07-25T20:24:26UTC /CN=HOSTNAME
0x2021 2017-09-20T21:54:51UTC 2022-09-20T21:54:51UTC /CN=HOSTNAME               0x3FC8 2020-10-27T19:47:26UTC 2025-10-27T19:47:26UTC /CN=HOSTNAME
0x5695 2023-10-17T19:37:27UTC 2028-10-16T19:37:27UTC /CN=HOSTNAME               0x68D2 2025-06-15T13:50:46UTC 2030-06-15T13:50:46UTC /CN=HOSTNAME
0x68D3 2025-06-15T14:57:37UTC 2030-06-15T14:57:37UTC /CN=HOSTNAME

It should have cleaned the cert.
