Remove Audit references

We do not have an Audit Filter yet

couple more refs in the excalidraw overview illustrations of filter chains

edit: sorted

We don't have an audit filter/plugin but it is exactly the sort of use case we want the proxy to support. Do you think we should only show what we currently have?

nit.

Suggested change

	<p class="lead">Topic encryption, policy-enforcement, multi-tenancy and much more.</p>
	<p class="lead">Record encryption, policy-enforcement, multi-tenancy and much more.</p>

On second thoughts, a decision maker might not necessarily know that Kafka refers to its application messages as records. "Encryption of topic records", "Topic record encryption"?

[robobario]

Maybe we should say encryption-at-rest to point to the bigger thing we enable here? If we use either Topic or Record they're both Kafka concepts, so I would go with Record Encryption to line up with our documentation. Though arguably some users like Operators might only think about Kafka in terms of Topics.

Anyway, can defer it from this PR

I think removing the reference is the right thing. This phrase could potentially disappoint a potential user.

Yeah that was my feeling, we talk about it in the same breath as other Filters we do offer, so it would be annoying to find this is the only one with no references in the documentation.

So I get what you mean that there's an audience who might be interested in the possibilities as a Filter Author, but currently it's confusing to have it mentioned in our highest level overviews and especially the hero banner on the landing page.

Yeah I see the concern.

I guess I've got a lot of the audit proposal in my head so the timing seems odd but I'm fine with merging

[robobario]

Could be worth merging this since Audit landing time is still unclear
