Update to spacytextblob v5

[bradley-erickson]

There are some breaking changes in spacytextblob==5.0.0 that we need to address. When running the positive or negative tone attributes, we get a not very useful error [E046] Can't retrieve unregistered extension attribute 'assessments'. Did you forget to call the set_extension method?. We do not get this error on previous versions.

This is likely due to the changes introduced in v5. See the comment included in v5's release below

Removed support for accessing ..polarity, ..sentiment, ..subjectivity, and ..assessments. Now, only the ..blob attribute is exposed. All other textblob attributes should be access through it. For example: ..blob.polarity, ..blob.sentiment, ..blob.subjectivity, and ._.blob.sentiment_assessments.assessments. This simplifies the code base and makes it easier to maintain. Lastly, this means that the config option {"blob_only": bool} was removed.
