Packages having a name starting with "http" are interpreted as URL and incorrrectly parsed from requirements.txt

[mmtevelde]

Describe the bug

My project uses requirements.txt to define dependencies. We use the httpx library. When running deptry, it incorrectly parses this entry as a dependency specified from URL:

$ grep httpx requirements.txt
httpx==0.25.2
$ pre-commit run --all-files
Could not parse dependency name from url httpx==0.25.2

The dependency parser incorrectly interprets the line as containing a URL.

Subsequently it throws a DEP003 because the dependency is imported but not detected as being specified in the requirements.txt (even though it is there): sample.py:1:0: DEP003 'httpx' imported but it is a transitive dependency.

As a workaround, I have added an ignore to my pyproject.toml:

[tool.deptry.per_rule_ignores]
DEP003 = ["httpx"]

I think a fix would be to improve the _line_is_url function or its regex here
Maybe changing the matcher from http|https to http://|https:// would fix the problem without impacting the intended functionality.

To Reproduce

Steps to reproduce the behavior:

1. Specify requirements.txt dependency starting with http
2. Optional - Import this dependency somewhere in your code
3. Run deptry
