chore(docs): Correct API docs for update order

[Tlazypanda]

Fixes #6451

Short description of what this resolves:

The PATCH request for orders API docs shows identifier instead of the id as the value of id in body of the request, which actually shows an error when used.

Changes proposed in this pull request:

• Api docs corrected replacing identifier with id.

@iamareebjamal I think it's good to merge.

@prateekj117 What's the difference between this and #6462

[prateekj117]

@iamareebjamal The tests were failing last time I checked that PR. And @mrsaicharan1 also commented on that regarding the same. My fault I didn't saw the file changes, they are right. No idea why the tests were failing then.

[iamareebjamal]

No other place requires changes?

[prateekj117]

I think.
