feat: Improve Performance of ` delete` Command with Concurrency

[bupd]

Fixes: #79

Description:

This PR enhances the performance of the harbor project delete command by introducing concurrency to handle multiple project deletions in parallel. The changes ensure that the command is more efficient, especially when dealing with multiple projects.

Changes:

• Concurrency Implementation:
• Added goroutines to execute runDeleteProject concurrently for each project specified in the command arguments.

Error Handling:

• Implemented an error channel (errChan) to collect errors from each goroutine.
• Ensured all errors are logged appropriately after all goroutines have completed.

Benefits:

• Performance: By running deletions concurrently, the command execution time is significantly reduced when dealing with multiple projects.
• Reliability: Enhanced error handling ensures that all errors are captured and logged, providing better visibility into potential issues.

Testing:

• [x] Tested the command without args and with multiple project names to ensure concurrent deletions work as expected.

Example Usage:

# Delete multiple projects concurrently
harbor project delete project1 project2 project3

# Delete a single project by prompting the user
harbor project delete

Before:

• The delete commands not have multiple deletion at a time.

After:

• The delete commands deletes multiple resources at a time.

Could you add multiple selection in the TUI.

Currently working on TUI multiple selection.

Will squash the commits.

I am planning to add the multiple TUI selection as a base component in separate PR. which can be used by multiple commands that support multiple selection and their associated action with that we can mimic the behavior of multiple select and action in TUI.
