Loosen certifi version requirements (#45)

Summary:
The certifi package has a "vulnerability" [0], asking us to update. Dependabot should take care of that, except it didn't:
```
  > updater | 2024/07/05 <job_852060501> Checking if certifi 2023.11.17 needs updating
  >   proxy | 2024/07/05  GET https://pypi.org:443/simple/certifi/
  >   proxy | 2024/07/05  200 https://pypi.org:443/simple/certifi/
  > updater | 2024/07/05 <job_852060501> Filtered out 2 yanked versions
  > updater | 2024/07/05 <job_852060501> Latest version is 2024.7.4
  > updater | 2024/07/05 <job_852060501> Requirements to unlock update_not_possible
  > updater | 2024/07/05 <job_852060501> Requirements update strategy lockfile_only
  > updater | 2024/07/05 <job_852060501> No update possible for certifi 2023.11.17
```

I suspect that reason is that it interprets the version as a SemVer specification and 2023 -> 2024 would be a major bump and it won't do that given our strategy.
It appears none of our Python code is actually depending on this package, so let's just remove it.
