Configuration

Operating system: Ubuntu 18.04 LTS

PlatformIO Version (platformio --version): PlatformIO Core, version 6.0.2

Description of problem

The HISTORY.rst file claims that PlatformIO's minimum Python version is 3.6 but pio package publish requires 3.7 because it uses str.isascii().

(Ideally the Python code should be automatically checked to determine if it can be run on older versions of Python.)

Steps to Reproduce

1. Run pio package publish with python 3.6

Actual Results

...
  File "/home/simon/.local/lib/python3.6/site-packages/platformio/package/commands/publish.py", line 116, in package_publish_cmd
    check_archive_file_names(archive_path)
  File "/home/simon/.local/lib/python3.6/site-packages/platformio/package/commands/publish.py", line 152, in check_archive_file_names
    if not name.isascii():
AttributeError: 'str' object has no attribute 'isascii'

Expected Results

Package is published
