2.4.4 doesn't consider dependencies that stopped shipping a wheel

[hynek]

• I have searched the issue tracker and believe that this is not a duplicate.

Steps to reproduce

Have a project with a dependency on a package that used to ship a wheel but doesn't anymore – like sqlanydb, the bane of my existence – and lock:

pyproject.toml

[tool.pdm]

[project]
name = "pdm-test"
version = "0"
dependencies = ["sqlanydb"]

gives this pdm.lock with pdm 2.4.4:

# This file is @generated by PDM.
# It is not intended for manual editing.

[[package]]
name = "sqlanydb"
version = "1.0.6.1"
summary = "pure Python SQL Anywhere database interface"

[metadata]
lock_version = "4.1"
content_hash = "sha256:c54813971e8f4b1fd69452c8720a2c8e56bad23b797371f42385df93415b21cf"

[metadata.files]
"sqlanydb 1.0.6.1" = [
    {url = "https://pypi.vm.ag/root/pypi/+f/747/03a7e495998b4/sqlanydb-1.0.6.1-py2.py3-none-any.whl", hash = "sha256:74703a7e495998b45566823ff5fa73509c75463b1d966456592bffca74b508ed"},
    {url = "https://pypi.vm.ag/root/pypi/+f/cf2/8a9a5da560af8/sqlanydb-1.0.6.1.tar.gz", hash = "sha256:cf28a9a5da560af8ef03b15095acc2f78a7bd94c8be3287a333fae1d02a21406"},
]

while pdm 2.4.3 gives you:

# This file is @generated by PDM.
# It is not intended for manual editing.

[[package]]
name = "sqlanydb"
version = "1.0.11"
summary = "pure Python SQL Anywhere database interface"

[metadata]
lock_version = "4.1"
content_hash = "sha256:c54813971e8f4b1fd69452c8720a2c8e56bad23b797371f42385df93415b21cf"

[metadata.files]
"sqlanydb 1.0.11" = [
    {url = "https://pypi.vm.ag/root/pypi/+f/5e6/0e1808b9c10f3/sqlanydb-1.0.11.tar.gz", hash = "sha256:5e60e1808b9c10f3afac9b294daaac1e189ad2ffdb9bb7ff9ac653427a4c5c7b"},
]

Actual behavior

As of 2.4.4, it locks to the last wheel-carrying version (in this case 1.0.6.1).

Expected behavior

It locks to the latest version (1.0.11).
