Bug description

Using the blog plugin with the language set to pt-BR, there is a problem with the babel format_date, with the given locale.

The locale is set by getting the langauge config, in this case pt-BR, but babel does not support the hifen (it must be an undescore). So ther error happens.

Line 803 from https://github.com/squidfunk/mkdocs-material/blob/master/src/plugins/blog/plugin.py

This error problably happens with other languages with hifen (e.g. ku-IQ)

The solution would be to replace the hifen (-) with (_)
