Feature: Project creation wizard

[CGoodwin90]

Implements an interactive project creation wizard, allowing users to create projects through a guided step-by-step process. The wizard is utilizing https://github.com/charmbracelet/huh for form structure & prompts.

Adds a new --interactive flag to the lagoon add project command. It's currently feature flagged behind the experimental flag introduced in #462. Adds the wizard & theme-ing logic in the internal/wizard/ directory.

The wizard gathers all mandatory fields for project creation, with the option to add additional fields. Input validation occurs for projectName, gitUrl, quotas, deploytargets etc. On success, the equivalent CLI command for the project creaton is generated & output for reference and re-use.
