Use alternate pdns-recursor image

[walkah]

Fixes #596

I'm not sure why the official pdns-recursor image fails to run Docker for Mac (M1's at least) but I found an alternate image that seems to work okay. Works for me ™️

Tested this out and PowerDNS runs without the exception we saw in #596.

Also, dig runfission.test returns the expected response:

runfission.test.	2380	IN	SOA	a.misconfigured.dns.server.invalid. hostmaster.runfission.test. 0 10800 3600 604800 3600

Maybe a separate issue, but runfission.test doesn't resolve with curl or in the browser. Server is running, and I've included 127.0.0.1 in my DNS hosts.

Did you add an A record for runfission.test ? The README instructions to just create the zone doesn't actually add any records, so this is probably fine.

I did not! That seems like the most likely explanation. 👍
