Fail to parse a private repo URI w/ credentials containing `.`

[ci-builder-onixs]

Issue description

I have the source defined in my Pipfile:

[[source]]
url = "https://${ARTIFACTORY_USER}:${ARTIFACTORY_API_KEY}@private.jfrog.io/artifactory/api/pypi/pypi-ci/simple"
verify_ssl = true
name = "my"

My username (in the ARTIFACTORY_USER envvar) contains a dot character (e.g. my.user).

Expected result

pipenv install dependencies.

Actual result

Pipfile.lock not found, creating...
Locking [packages] dependencies...
Building requirements...
Resolving dependencies...
✘ Locking Failed!

Steps to replicate

1. Add a private repo w/ a username containing . symbol in it
2. Try pipenv install any deps from the added source

@ci-builder-onixs can you open a report in requirementslib linked to this issue?

[matteius]

@ci-builder-onixs I think this issue may be addressed on my future oriented requirementslib branch: #5679
