Bump aesara dependency

[keesterbrugge]

What is this PR about?
Bumping aesara from 2.7.5

The reason is that pypi is able to properly extract the dependencies of aesara >=2.7.6, but not of 2.7.5, see this ticket for more info. So AFAICT with this change pymc and all it's dependencies will be properly added to our pypi-mirror by just adding pymc to it and will be installable with just pip install pymc :D

Thanks for the awesome library!

Looks like there were two breaking API changes not mentioned in the release notes of the patch version. (at.unbroadcast and at.patternbroadcast)

Did they originate from aesara-devs/aesara#915?
Maybe @ricardoV94 knows how to work around these API breaks?

I'm taking a look!
