Keep leading spaces in descriptions

[jnodorp-jaconi]

Currently, leading spaces are removed, when a section description is generated. This is problematic for code sections:

README.md

## Parameters

values.yaml

## @section MRE

## @descriptionStart
## ```yaml
## foo:
##   bar: baz
## ```
## @descriptionEnd

## @param foo
foo: bar

Result

## Parameters

### MRE

```yaml
foo:
bar: baz
```

| Name  | Description | Value |
| ----- | ----------- | ----- |
| `foo` |             | `bar` |

Expected Result

## Parameters

### MRE

```yaml
foo:
  bar: baz
```

| Name  | Description | Value |
| ----- | ----------- | ----- |
| `foo` |             | `bar` |

Sorry for my very late response

I've just created an internal task to work on this issue. I hope to come back soon.
