Scheduled weekly dependency update for week 15

[pyup-bot]

Update bleach from 4.1.0 to 5.0.0.

Changelog

5.0.0

-------------------------------

**Backwards incompatible changes**

* ``clean`` and ``linkify`` now preserve the order of HTML attributes. Thank
you, askoretskly! (566)

* Drop support for Python 3.6. Thank you, hugovk! (629)

* CSS sanitization in style tags is completely different now. If you're using
Bleach ``clean`` to sanitize css in style tags, you'll need to update your
code and you'll need to install the ``css`` extras::

   pip install 'bleach[css]'

See `the documentation on sanitizing CSS for how to do it
<https://bleach.readthedocs.io/en/latest/clean.html#sanitizing-css>`_. (633)

**Bug fixes**

* Rework dev dependencies. We no longer have
``requirements-dev.in``/``requirements-dev.txt``. Instead, we're using
``dev`` extras.

See `development docs <https://bleach.readthedocs.io/en/latest/dev.html>`_
for more details. (620)

* Add newline when dropping block-level tags. Thank you, jvanasco! (369)
