semver minimum version requirement

[vdorie]

dlt version

1.4.0

Describe the problem

semver is listed as requiring >=2.13.0, however semver.Version (referenced in a few places, including here) was only introduced with version 3.0.0. This causes dlt to fail at import on systems with semver already installed at 2.13.0, giving:

AttributeError: module 'semver' has no attribute 'Version'

Expected behavior

dlt should be able to be used on systems that meet its stated requirements.

Steps to reproduce

python3 -m venv test_env
source test_env/bin/activate
pip install semver==2.13.0 dlt

import dlt

Operating system

Linux, macOS

Runtime environment

Local

Python version

3.11

Additional information

It looks as if semver.Version was introduced with 47633c6, so the issue also impacts 1.3.0.
