v3.0.1 Bugfix Release

Small bugfix for the get_locale() behaviour when the default locale is returned.

v3.0.0

Major version bump as this version removes support for Python 3.5 and 3.6, along with multiple
major breaking changes. Hope you've been following SemVer :)

• Dropped support for end-of-life Python 3.5 and 3.6, added tests for 3.10 and 3.11.
• Fixes to documentation to address outdated links and settings (#204, 201)
• Jinja version 3 or greater is now required (released 2021)
• Removed Babel._date_formats, use the public Babel.date_formats instead.
• list_translations() always returns the default locale, even if it does not exist. (#75)
• Add lazy_npgettext() (#68)
• Babel.locale_selector and Babel.timezone_selector no longer exist. They must be provided
  either when the Babel() object is created or when init_app() is called. This is to support
  having a single Babel object for multiple Flask apps (#107) as well as to simplify settings
  and multi-threaded state.
• Most configuration options can be passed directly through init_app().

• Documentation moved from python-hosted to Github Pages.
• CI moved from Travisci to Github Actions
