Changed most yml to yaml, except for this one:

`The following example `scrape_config` adds to `prometheus.yml`:

And this one:

|YAML
| `com.fasterxml.jackson.core:jackson-databind` + `com.fasterxml.jackson.dataformat:jackson-dataformat-yaml`
| `log4j2.yaml` + `log4j2.yml`

|JSON
| `com.fasterxml.jackson.core:jackson-databind`
| `log4j2.json` + `log4j2.jsn`
|===

The prometheus docs refer to their config file as prometheus.yml.

The log4j example looks consistent enough with what is below it.
