Pluploader

This is maintenance release, fixing comparability with python 3.11.

What's Changed
* poetry: update dependencies by craftamap in https://github.com/craftamap/pluploader/pull/75
* build(deps): bump lxml from 4.7.1 to 4.9.1 by dependabot in https://github.com/craftamap/pluploader/pull/76
* Install cloud error handling by craftamap in https://github.com/craftamap/pluploader/pull/79

Release v0.8.1 brings a bugfix, as well as updates to the dependencies.

- A workaround regarding versions containing -SNAPSHOT got added. Previously, if a plugin snapshot got or was installed, the parsing library comparing the installed version with the new version failed, as it expects a python-like version string. For now, -SNAPSHOT get's replaced with .dev when parsing.
- All dependencies got bumped to their newest minor version automatically.
- importlib-metadata is updated, which allows pluploader to be installed on newer Python versions (3.9+) without causing issues.

- Removed Lively Apps Logo, and overall Lively Apps branding
- Added Feature to Manage Access Token (aka Cloud Developer Licenses)
- Added a Warning displaying if the version currently installed is higher than the installing one
- Updated GIFs in the README

- 🐛 `install --mpac-key/--mpac-id`: fixed bug due to changes in the marketplace api. Previously, the feature did not work, as the file name missed the file extension.

With pluploader 0.6.0, the following features come to you:
- Added option `--cloud` to `pluploader install`. This allows you to install app descriptors of connect apps to your confluence. Note that `pluploader list`, `pluploader info` and `pluploader uninstall` already work with the atlassian cloud.
- Added the ability to download apps from the atlassian marketplace by providing an app key or an mpac-id. Take a look into `pluploader install --help` to see how you can use `--mpac-id` and `--mpac-key`.
- Added app licensing feature. Use `pluploader license --help` to see how you can use `pluploader license timebomb`, `pluploader license update`, `pluploader license info` and `pluploader license delete`.
- Added basic environment variables support. You can use `PLUP_BASEURL`, `PLUP_USER` and `PLUP_PASSWORD` to specify baseurl, username and password instead of using the command line arguments or a configuration file.

Under the hood:
- A bit of refactoring all over the place.
- our implementation of the upm-api is now class-based instead of functional-based.
- we are now using superlinter by github for our pipeline and pull requests
