Update logo of Foundation

[potiuk]

The logo of Foundation has been changed to Oak leaf. While HTTPD changes their logo to follow, we should replace the feather with oak logo of the ASF.

Dear maintainers - would you please merge it and re-publish the documentation at https://hub.docker.com/_/httpd ?

[tianon]

Our publishing process (and Docker Hub itself) box this logo into a square - is there a variant of the logo that fits better into a square shape, or is this really the preferred form? (I don't mind either way if this is the right one to use, but I do want to double check ❤️)

[tianon]

For example, would it be appropriate for us to use https://apache.org/foundation/press/kit/feather.svg instead? That will fit into a square better (and our tooling will handle an SVG nicely so that we can get whatever size we need).

[tianon]

(even https://apache.org/foundation/press/kit/poweredBy/Apache_PoweredBy.svg seems like it'd be better/cleaner for our purposes, but we really are open to whatever is preferred 🙇)

[potiuk]

Indeed - powered-by-the-asf logo seems best for that purpose.

Nice, thanks for confirming! While we've got this open I'd prefer to swap to https://apache.org/foundation/press/kit/poweredBy/Apache_PoweredBy.svg (saved as logo.svg in this same directory) -- is that something you're willing to do, or would you rather I/we take over from here? 🙇 ❤️

[potiuk]

Pushed. I did not know you can have .svg there :)

[tianon]

Nice, thank you! 👍
