Re-export requirements.txt to fix version errors (#1099)

* Re-export requirements.txt to fix version errors

The version of lxml in this file had a known vulnerability that got
caught by the "safety" checker, but it is updated in the poetry files.

Regenerated using:
https://github.com/usds/justice40-tool/tree/main/data/data-pipeline#miscellaneous

* Fix lint error

* Run lint on all envs and add comments

* Ignore testst that fail lint because of dev deps

* Ignore medium.com in link checker
