Issue #, if available:

Description of changes:

The README.md states that this utility is only compatible with Python
v3.10 thru v3.13, however there was no upper bound specified in the
pyproject.toml definition.

It is currently therefore possible to install cfn-lint using Python
3.14 but it will throw various errors and / or warnings when being
executed.

This change adds an upper bound so that installation of cfn-lint will
fail on versions of Python that are unsupported.
