DOC: read_excel supports skiprows argument like read_csv, but tests and docs needed

Documentation problem

In read_csv, we say that we support:
skiprows list-like, int or callable, optional

Line numbers to skip (0-indexed) or number of lines to skip (int) at the start of the file.

If callable, the callable function will be evaluated against the row indices, returning True
if the row should be skipped and False otherwise. An example of a valid callable argument
would be lambda x: x in [0, 2].

In read_excel, we say that we support:

skiprows list-like

Rows to skip at the beginning (0-indexed).

It turns out that the int and callable arguments work fine with read_excel(), so we should indicate that in the documentation.
We also need to add tests for those 2 cases.

Suggested fix for documentation and additional tests

• copy the read_csv doc for skiprows over to read_excel
• add tests to tests/io/excel/test_readers.py for the int and callable options

I'd like to try this out. How do I assign the issue to myself?

@Dr-Irv I've submitted a PR (#36437) for this, and it has passed all CI checks except one: the travis-ci check is failing due to a stalled build (?).

conda env create -q --file=ci/deps/travis-37-cov.yaml

Collecting package metadata (repodata.json): ...working... done

Solving environment: ...working... 

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.

Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#build-times-out-because-no-output-was-received

The build has been terminated
