Base Config Setup filepath issue

[Mtaylert]

How to reproduce the behaviour

When initializing my configuration file, I set my train and dev paths as follows in my base_config.cfg:

train = 'data/train.spacy'
dev = 'data/valid.spacy'

After running python -m spacy init fill-config ./base_config.cfg ./config.cfg, the single quotes wrapping each file path result in the following

train = "'data/train.spacy'"
dev = "'data/valid.spacy'"

I'm wondering if there should be a fix to accept single quotes as a string wrappers instead of assume it is part of the literal path.

I think the issue is that the values are parsed as JSON and JSON only supports double quotes. See: https://thinc.ai/docs/usage-config.

So I don't think we want to try to modify this behavior, but we can definitely think about how to document it more clearly.

It's been a long time since this issue was raised, but thanks for bringing it up - I just added a check to confection in that should warn in cases like this in the future.
