Example does not work with pydantic >1.9

[apirogov]

I could not run the example in the README:

from pydantic_schemaorg.ScholarlyArticle import ScholarlyArticle
scholarly_article = ScholarlyArticle(url='https://github.com/lexiq-legal/pydantic_schemaorg',
                                        sameAs='https://github.com/lexiq-legal/pydantic_schemaorg',
                                        copyrightNotice='Free to use under the MIT license',
                                        dateCreated='15-12-2021')

raises for me

@apirogov I see that it an issue on python < 3.9. Switching to python 3.9 can resolve your issue.

In the mean time i will put this issue on the backlog

I'm having this as well. downgrading to pydantic==1.9.0 did not solve this. we are using python 3.8
