Move requirements file to pyproject.toml

[ravi-kumar-pilla]

Description

Migrate package dependencies from requirements.txt to pyproject.toml

Context

This ticket continues on the effort to improve Kedro-Viz packaging after #1978 and #1967 are merged.

Possible Implementation

• Move the dependencies in requirements.txt to pyproject.toml under [project] -> dependencies
• Move the dependencies in test_requirements.txt to pyproject.toml under [project.optional-dependencies] -> test
• Update CI tests to install dependencies via toml file using pip install . (for core dependencies), pip install .[test] (for test dependencies).

NOTE: There might be issues of kedro-viz being installed along with the dependencies. There is an open PR to address this issue - pypa/pip#11440
