poetry init Unable to Find Package During Interactive Dependency Addition

### Description

When using the `poetry init` command to create a new project, the interactive dependency addition step fails to find packages (e.g., `numpy`). However, the poetry add command works as expected for the same package. The issue appears to be related to how `poetry init` handles package search and HTTP requests.

### Workarounds

After completing the poetry init process, dependencies can be added using the poetry add command. For example:`poetry add numpy`. This bypasses the issue with the interactive dependency search step.

### Example pyproject.toml

```TOML
The issue occurs during the poetry init process, so no pyproject.toml file is generated yet.


# Example pyproject.toml that would have been generated if the issue did not occur
[tool.poetry]

readme = "README.md"

[tool.poetry.dependencies]

numpy = "^1.26.0"  # This dependency cannot be added during the `poetry init` process


[build-system]
requires = ["poetry-core"]
