"""Find the end position of the import section in a list of code lines.

This function iterates through a list of code lines to determine where the import section ends. The import section includes lines that start with 'import ', 'from ', 'sys.path.', or 'load_dotenv('. The function skips over docstrings, comments, and empty lines while identifying the import section.

Args:
    lines (List[str]): A list of strings representing the lines of code.

Returns:
    int: The index of the line immediately after the last import statement. If no import statements are found, returns 0.

The function handles the following cases:
- Single or multiple import statements.
- Import statements followed by non-import statements.
- Docstrings and comments within the import section.
"""
You should write code starting with:
from typing import List

def find_import_section_end(lines: List[str]) -> int:
