## Reverse
Given a sample.yml file of:
```yaml
- 1
- 2
- 3
```
then
```bash
yq 'reverse' sample.yml
```
will output
```yaml
- 3
- 2
- 1
```

Given a sample.yml file of:
```yaml
- a: banana
- a: cat
- a: apple
```
then
```bash
yq 'sort_by(.a) | reverse' sample.yml
```
will output
```yaml
- a: cat
- a: banana
- a: apple
```
