Specify more recent awscli dependency to avoid dependency resolution issues

• I read the documentation (readme and wiki).
• I searched other issues (including closed issues) and could not find any to be related. If you find related issues post them below or directly add your issue to the most related one.
• I confirm that this bug report does not report on a specific news site where news-please does not work. Please keep in mind that news-please is a generic crawler so it is expected that it will not work for all sites well or even at all.

Describe the bug
news-please depends on awscli>=1.11.117, but versions this old have broken metadata on PyPi. Using a package manager that tries to resolve dependencies (such as Poetry) will therefore have to download and inspect every single awscli version that has been published since about 2017. My last poetry lock took 3.5 hours. This issue can be fixed by simply depending on a more recent version (no earlier than October 2021, see aws/aws-cli#5701).

I would suggest to simply depend on the most recent at the time, i.e., awscli>=1.27.78.

Does this have any side effects, e.g., the more recent awscli version having dependency conflicts with NP?

Not I know of.
