DOC: update the DataFrame.reindex_like docstring
State: closed

- [x] The PEP8 style check passes: git diff upstream/master -u -- "*.py" | flake8 --diff
- [x] The html version looks good: python doc/make.py --single <your-function-or-method>
- [ ] The validation script passes: scripts/validate_docstrings.py <your-function-or-method>
Errors due to the fact that this method `.reindex_like()`can use the same input parameters as `.reindex()` (I avoided copy/paste and referred to the other method instead)
```
        Errors in parameters section
                Parameter "other" has no description
                Parameter "method" has no description
                Parameter "copy" has no description
```
