chore(__init__.py): Update version to 1.2.0 and refactor init method

method of the SimpleCache class has been refactored to enforce the
requirement of passing a Provider object during initialization.

chore(simple_cache): Update package version to 1.1.2

- Update the package version in __init__.py to reflect the latest release
- and ensure consistency with the project's versioning scheme

fix(tests): Remove access to attribute value in cache test

- Removed access to attribute 'value' as it's unnecessary and causing
  incorrect cache behavior. Now the test obtains the correct values from the
  functions directly.

chore(pyproject): Update project description

This commit updates the project description in the pyproject.toml file.
The description now reflects that Simple Cache is designed to simplify caching
operations using providers instead of specifically mentioning Deta Base.
This change aims to provide a more generic and flexible description of the
project's functionality.

feat: Update pyproject.toml

- Update version to dynamic value
- Add dynamic version attribute using setuptools
- Add project URLs for homepage and issues

The pyproject.toml file was updated to make the version value dynamic, allowing it to be automatically updated.

Additionally, the dynamic version attribute was added using setuptools, enabling the project to automatically retrieve the version from the `simple_cache.__version__` attribute.

Finally, project URLs were included to provide easy access to the project's homepage and issue tracker.
