Adding nats micro example for Rust

[autodidaddict]

Adds an example for micro/intro in Rust. The change to the rust Dockerfile is, for some odd reason, required in order to allow output to show up from running the Rust examples (thanks @Jarema)

Ugh, the output is empty.. same weird side effect with other Rust examples.. until we figure this out, let's generate the recording locally and commit. The CI will use that if present rather than generate one.

There is another PR somewhere that @Jarema pushed that actually fixes the output problem. Will generate locally

w00t! :partying_face: the bullets rendered properly.

It seems to have ignored the manually created output.txt

[bruth]

Still no output 🙁

[bruth]

Ah needs the output.cast also

[bruth]

A condition that checks for one but not the other..

[Jarema]

I will take a deeper look tomorrow in that generation issue with Docker

[autodidaddict]

@Jarema @bruth I'd like to get this merged.. please let me know what I can do in order to get the CI to pass here.

[bruth]

@Jarema pushed a commit to the fix-rust-output branch a few days ago that you can merge in here to test if it fixes the issue.

[Jarema]

Ok. Will work on this one today.

These look like Python failures, which is weird... https://github.com/ConnectEverything/nats-by-example/actions/runs/6615260740/job/17967034931?pr=144#step:8:2174
