1.1 and 1.3 are broken, deprecate them

[maelvls]

As detailed in GoogleCloudPlatform/marketplace-k8s-app-tools#566, a misplaced field info in the old deployer's Application manifest makes it impossible to install version 1.1 and 1.3 on the Marketplace.

Note that the default version is now 1.4: new users that want to install jetstack-secure-for-cert-manager won't be affected unless they manually select 1.3 or 1.1.

Two options:

• Either we build and submit two new deployer images (1.1.0-gcm.9 and 1.3.1-gcm.1), but I don't think these versions are going to be installed anyways,

• Or we "deprecate" 1.1 and 1.3, but the minimum deprecation notice on the Marketplace is 6 months (I tried changing the deprecation date to an earlier date and it would always come back to 14 January 2022):

  

  For 6 months, users will still be able to select either 1.1 or 1.3 (although being marked as deprecated) and will see their deployment fail with the error:

      error: error validating "/data/resources.yaml": error validating data:
      ValidationError(Application.spec.descriptor): unknown field "info" in
      io.k8s.app.v1beta1.Application.spec.descriptor; if you choose to ignore
      these errors, turn validation off with --validate=false
  

But since I am 99% confident that people won't choose 1.3 or 1.1 (there is no reason to use those versions), I think we can just mark these versions as deprecated and wait for 6 months before they disappear.

I deprecated 1.1 and 1.3 and re-submitted them for review.

I will add a notice:

• on the GitHub Release pages,
• on the README for the click-to-deploy and command-line installation methods (Add a deprecation warning for 1.1 and 1.3 #60).
