Proposed documentation enhancement

Currently, the doctoring for the picks parameter of .get_data() reads:

picksstr | array_like | slice | None

Channels to include. Slices and lists of integers will be interpreted as channel indices. In lists, channel type strings (e.g., ['meg', 'eeg']) will pick channels of those types, channel name strings (e.g., ['MEG0111', 'MEG2623'] will pick the given channels. Can also be the string values “all” to pick all channels, or “data” to pick data channels. None (default) will pick all channels. Note that channels in info['bads'] will be included if their names or indices are explicitly provided.

See e.g. https://mne.tools/dev/generated/mne.Epochs.html#mne.Epochs.get_data

I always assumed that bad channels are not included by default (None), as I didn't provide their names or indices. But that doesn't seem to be the case.

The doctoring should be updated to explicitly state that by default, bads will be included.

This also suggests that we should take a look at our tutorials that make use of .get_data() and update them to pass picks="data" or similar.

We may also need to take a look at the decoding steps of MNE-BIDS-Pipeline, which use .get_data(), too.

Edit: In most (all?) tutorials we run inst.pick(..., exclude="bads"), which avoids the issue mentioned above.
