chore(packaging): ensure well-named post-weld packages

[danceratopz]

As of #1377, the ethereum-execution package now additionally contains all EEST libraries and pytest plugins.

In particular, ethereum-execution will contain two packages with extremely generic names (cli and config) that we should consider renaming:

execution-specs/pyproject.toml

Lines 31 to 34 in 68b8df5

	[tool.setuptools.package-dir]
	"" = "src"
	cli = "src/ethereum_spec_tests/cli"
	config = "src/ethereum_spec_tests/config"

Suggestion: Rename the packages as below in EEST, then follow-up with a PR in EELS to update the sub-trees and its pyproject.toml:

• cli -> ethereum_test_cli.
• config -> ethereum_test_config.
• ethereum_test_clis -> ethereum_test_client_clis.
