Add Password Provider

[laba-ehehe]

What does this change

This pull request adds a new feature to the Faker library: a strong password generator. It introduces a new provider, faker/providers/password, with a strong_password method. The new method allows users to generate passwords that meet specific security policies, which is useful for testing common real-world login and signup scenarios.

What was wrong

Nothing was wrong. The Faker library previously did not have a provider for generating passwords that meet customizable security policies.

How this fixes it

This PR resolves the issue by implementing a new strong_password method with flexible parameters. Users can now specify the total length of the password and a minimum number of min_upper, min_lower, min_digits, and min_symbols. The method also includes an allow_ambiguous flag to exclude commonly confused characters by default. Comprehensive unit tests have been included to ensure the functionality is correct and all specified constraints are met.

Fixes #2240
