chore: dropping py37 support in favor of py312

[kiraum]

Hello! In a nutshell:

I recently attempted to build irrexplorer on py312, and had issues due frozenlist==1.3.3 not be supported/build for py312.
They started to support py312 on fronzenlist==1.4.0 onwards, due that, the proposed solution is to drop py37 support that's already end of life since 2023-06-27 in favor of py312.

To resolve this issue and enable support for py312, I propose the following changes:

• Drop support for py37 in favor of py312. This will allow us to use the latest version of Python, and frozenlist compatibility will no longer be an issue.

• Update the CircleCI pipeline configuration to reflect the changes in supported Python versions. However, I don't have access to the CircleCI pipeline, so this needs to be double-checked and updated accordingly.

• I've included updated frontend/yarn.lock and poetry.lock files to include the necessary dependencies generated based in the new project requirements. I noticed that in the file history, these files have been updated both manually and automatically. Please ensure that the appropriate method is used to update these files.

• Update the README file to reflect the changes in supported Python versions, updating supported Python version from 3.8 onwards.

• Update the pyproject.toml file to specify the new Python version requirements.

From poetry:

The current project's supported Python range (>=3.7,<4.0) is not compatible with some of the required packages Python requirement:
  - frozenlist requires Python >=3.8, so it will not be satisfied for Python >=3.7,<3.8

Because irrexplorer depends on frozenlist (1.4.1) which requires Python >=3.8, version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

Thanks for this amazing project!
