Show dependencies in package-detail pages

[toshihikoyanase]

Motivation

Detailed pages of the OptunaHub packages sometimes display installation command, such as:

pip install -r https://hub.optuna.org/samplers/name/requirements.txt

However, users cannot see the list of dependencies via Web UI. The goal of this feature proposal is to address this limitation.

Note that the original idea for this feature proposal was suggested by @c-bata .

Description

If a requirements.txt file exists for a package on OptunaHub, we propose to display its contents as a list in the Installation section of the corresponding package-detail page.
The list may sometimes be lengthy, and we suggest employing the details tag, which allows users to expand and view the full list of dependencies.

Here's a potential implementation:

## Installation


pip install -r https://hub.optuna.org/samplers/name/requirements.txt

<details>
  <summary>list of dependencies</summary>
  <!-- Import the contents of https://hub.optuna.org/samplers/name/requirements.txt here. -->
</details>
