docs for awsSigv4 does not render bullet points correctly

[Anurag252]

Docs for awsSigv4 does not gets rendered correctly.

• There is an extra _ in the AWS Sig V4 hyperlink and hence the hyperlink is broken.
• x-amz-accesskey , x-amz-secret, x-amz-time and x-amz-session all should have been bullet points.
• Service should also be a bullet point, whereas it is currently part of paragraph.

To Reproduce
Add context, for example:

1. visit https://opensource.zalando.com/skipper/reference/filters/#awssigv4
2. click on AWS Sig V4 hyperlink
3. observe x-amz-accesskey , x-amz-secret, x-amz-time, x-amz-session and Service.

Expected behavior

1. Hyperlink should be functional.
2. All bullet points should be on new lines.

Observed behavior

1. Hyperlink is broken.
2. Bullet points are part of paragraph.
