Consider adding one more indentation after if

Please consider the following different ways of writing if

```
{
replicas: {
build: if isCanary then 0
else 1,

dev: if isCanary then
0
else
1,

prod: if isCanary
then 0
else 1,

perf: if isCanary
then
0
else
1,

},
}
```
`jsonnet fmt` aligns `then` and `else` with the key name.

Did you consider adding one more indent to the blocks starting with `then` and `else`.
How about the following indentation assuming `--indent 4` is passed to `jsonnet fmt`

```
{
replicas: {
build: if isCanary then 0
else 1,

dev: if isCanary then
0
else
1,

prod: if isCanary
then 0
else 1,

perf: if isCanary
then
0
else
1,
},
}
```
