DOC: fixing GL08 errors for pandas.IntervalIndex.left, pandas.IntervalIndex.mid and pandas.IntervalIndex.length
All GL08 Errors resolved in the following cases:

scripts/validate_docstrings.py --format=actions --errors=GL08 pandas.IntervalIndex.left
scripts/validate_docstrings.py --format=actions --errors=GL08 pandas.IntervalIndex.mid
scripts/validate_docstrings.py --format=actions --errors=GL08 pandas.IntervalIndex.length

I want to know that what should I do next ? I am not sure what should I fix the error, because some of it I'm not really understand. Or should I just skip it? pre-commit.ci autofix @datapythonista just FYI there's an effort to minimize/remove docstring reuse (https://github.com/pandas-dev/pandas/pull/57683, https://github.com/pandas-dev/pandas/issues/57578) to minimize complexity of the docstring reuse mechanisms @j36426052 do you want to continue working in this PR? Besides addressing the comments you'll have to resolve the conflicts. Sorry that I'm not really sure what part I need to fix. The comment part, should I reuse some comment to let it's structure more complete. I'm not sure how to minimize/remove docstring. 

Also the comflict in Numpy Dev, it show "test-data.xml not found", but I don't see some document talk about this.

Or should I just skip the above I mention. Maybe you mean other comflict? As mroeschke said, there's no need to worry about reusing docstrings as they are trying to minimize docstring reuse.
Focus on applying the 3 suggested "general comments" first. Thanks for the pull request, but it appears to have gone stale. If interested in continuing, please merge in the main branch, address any review comments and/or failing tests, and we can reopen.
