Documentation for including failed data references the wrong key

[RaghavSood]

What did you do?

The include_failed parameter on various endpoints, such as transactions and operations, is documented as includefailed.

Example: https://developers.stellar.org/api/resources/get-operations-by-account-id

What did you expect to see?

The parameter key should be include_failed.

What did you see instead?

The documentation reflects it as includefailed.

Using the parameter as documented doesn't work

With include_failed: https://horizon.stellar.org/accounts/GBFVU7QY6EMTYSF3WKH54CO5CE46BC72HOKZBBXH5YBJBLDVT3RNSNM2/operations?cursor=122568453843611647&limit=2&include_failed=true

With includefailed: https://horizon.stellar.org/accounts/GBFVU7QY6EMTYSF3WKH54CO5CE46BC72HOKZBBXH5YBJBLDVT3RNSNM2/operations?cursor=122568453843611647&limit=2&includefailed=true

The transaction 3cdbcbef533c834095cee2719b812d51394f95043e17e0f92a5251faf5b318f5 is only reflected when the correct parameter name is used, as expected

@RaghavSood Thanks for pointing this out! I've opened a PR that should address this issue: #89

If possible, would you take a look at the preview to see if that has resolved the problem where you noticed it?

Edit: Here's the preview URL http://developers-pr89.previews.kube001.services.stellar-ops.com/

Done with #89
