The code are wrapped due to us using line-length=79 before, but now some
of the code can easily fit in 88 chars.
The formatter did not change this automatically when we changed line-length,
because of magic trailing commas that gets added when they turn into multiple lines.
Black/ruff wrapping them in parens and splitting them into multiple lines
was making it difficult to read.
* bump ruff to v0.0.247
* ruff: enable pep8-naming check
rename some camelCased APIs, especially in logger
rename G variables to graph
ignore some variable namings and help messages in dvc.commands
`pipeline list` is no more, it had some very questionable applications
(none to be precise) and was duplicating old `pipeline show` functionality.
We might introduce a different command to assist in listing (e.g. for
shell completion) in the future.
New `dvc dag` replaces `dvc pipeline show` and by-default will show
all pipelines in the project in ASCII (so there is no more --ascii)
and also `--dot` support, just like before. When given a target,
`dvc dag` (in any mode) will show DAG that leads to the target,
skipping the descendants, unless `--full` is specified.
