Description

The following command on Windows or Linux:
py -m idf_component_manager component pack
Produces a tgz archive that contains a folder with an empty name:
test_archive.tgz

ChatGPT says the following about this:

It contains a directory entry whose name is the absolute path / (root). Many tools reject or warn about archives with absolute paths for security reasons, which can make extraction fail or behave strangely.

Such archives also fail to open in tools like Directory Opus: Tgz archive can't be opened

To Reproduce

On Windows or Linux:
* Open any folder with an ESP-IDF component
* Run `py -m idf_component_manager component pack`
* Check the resulting `tgz` file.

Expected behaviour

It should produce a correct tgz file.
