When a user lands on this repo and reads the README or Quick Start Guide, the instructions
should point the user to the latest released version of the proxy, not the current dev version.

This PR updates make generate so that it does not automatically update the version in documentation,
leaving the latest release version in the docs.

It also updates the release-please-updates job that generates code after the release PR is
created to update the version in docs along with running make generate.

Update version.txt to the next dev version.

…ot (#158)

This updates the Quick Start guide adding a few extra steps to work around
the problem that the installer does not work on GKE Autopilot clusters.

This explains to the user how to use the helm chart for cert-manager to make it
install correctly on GKE.

Related to #157
Further work required: #162

The README should say that this software is not yet ready for production.

For security, AuthProxyWorkload resources are only allowed to affect workloads running
in the same namespace. This prevents one AuthProxyWorkload in one namespace from affecting
a workload in a different namespace.

This change removes the WorkloadSelectorSpec.Namespace field and associated code that allowed
cross-namespace workload selection.

The copyright header on generated files need to read the current year.

This updates the install script to use helm to install cert-manager. This makes the installer work both for
GKE Autopilot and non-autopilot clusters.

Fixes #157

The proxy release is complete. Now we must update the operator to deploy the proxy image 2.0.0.

Release-As: 0.2.0
