plistlib documentation should indicate that it base64-encodes data implicitly

Documentation (plistlib)

The plistlib documentation (see https://docs.python.org/3/library/plistlib.html) should indicate that it implicitly base64-encodes plist "data" values (which are indicated by the values being Python bytes objects).
See code at: https://github.com/python/cpython/blob/96f8d3619d839266491b722b943de65892bb0e81/Lib/plistlib.py#L369

The plist file specifications require data values to be encoded with base64. However, I was thinking that I have to do that before using the plistlib, and was wondering what happened (since the data was encoded twice then in the resulting plist file)...

阅读 https://docs.python.org/3/library/plistlib.html 上的 plistlib 文档，以及 Lib/plistlib.py 中 369 行附近引用的实现。更新文档，说明 Python bytes values 会在 plist data 中隐式进行 base64-encoded，因此用户无需预先对其进行编码。
