Literal "calamine" missing from ExcelFile engine attribute

[sanzoghenzo]

Describe the bug

#898 missed the engine attribute of the ExcelFile class.

To Reproduce

import pandas as pd

with pd.ExcelFile("path.xlsx", engine="calamine") as xlsx:
   pass

using mypy I got

error: Argument "engine" to "ExcelFile" has incompatible type "Literal['calamine']"; expected "Literal['xlrd', 'openpyxl', 'odf', 'pyxlsb'] | None"  [arg-type]

Please complete the following information:
I don't think it matters, but:

• OS: Windows 10 22H2
• python v3.10
• mypy v1.13.0
• pandas-stubs v2.2.3.241126

That is correct, it was missed there! Seems like a small addition to be made in the pandas-stubs/io/excel/_base.pyi. Open to PR with tests in tests/test_io.py.
