Case-sensitive package badge resolution (Fabric v fabric)

[destrys-noirlab]

I'm not certain this is a solvable issue, but here's what I've seen.

Using:

• renovate gitlab runner
• Python 3.10.3
• Poetry version 1.1.13

Steps:

• poetry add fabric (this adds Fabric to pyproject.toml, poetry will not resolve fabric)
• manually downgraded to 2.6.0
• ran renovate CI pipeline
• MR was created, with merge-confidence badges, but they are all dataless (examples below)
• Editing MR to use Fabric instead of fabric in the renovateapi urls shows the correct data

Current Behavior:

Package	Change	Age	Adoption	Passing	Confidence
Fabric (source, changelog)	2.6.0 -> 2.7.0

| Package | Change | Age | Adoption | Passing | Confidence |
|---|---|---|---|---|---|
| [Fabric](https://fabfile.org) ([source](https://github.com/fabric/fabric), [changelog](https://www.fabfile.org/changelog.html)) | `2.6.0` -> `2.7.0` | [![age](https://badges.renovateapi.com/packages/pypi/Fabric/2.7.0/age-slim)](https://docs.renovatebot.com/merge-confidence/) | [![adoption](https://badges.renovateapi.com/packages/pypi/Fabric/2.7.0/adoption-slim)](https://docs.renovatebot.com/merge-confidence/) | [![passing](https://badges.renovateapi.com/packages/pypi/Fabric/2.7.0/compatibility-slim/2.6.0)](https://docs.renovatebot.com/merge-confidence/) | [![confidence](https://badges.renovateapi.com/packages/pypi/Fabric/2.7.0/confidence-slim/2.6.0)](https://docs.renovatebot.com/merge-confidence/) |
