feat: wildcard match aliases

[vmaerten]

Summary

The wildcard did not match aliases.
I've done a bit of refactoring and moved some code into FindMatchingTasks, but its signature has changed. Is it OK for the package API, or should I consider another solution ?
The goal was for FindMatchingTasks to also handle matching aliases (even without wildcards). It felt more logical to group all the task-matching logic in one place.

Fixes #1900

NOTE: I modified the test, but I did not migrate it to the new system yet

Pull Request Overview

This PR introduces support for wildcard matching of task aliases by refactoring task-matching logic into a single function, FindMatchingTasks, and updating related components.

• Updated task definitions in Taskfile.yml to include alias patterns
• Modified WildcardMatch in taskfile/ast/task.go to iterate over both task names and aliases
• Adjusted FindMatchingTasks and GetTask in task.go to handle conflicts when matching aliases

[nitpick] Consider renaming 'names' to 'candidateNames' to improve clarity when iterating over both task names and aliases.

Suggested change

	names := append([]string{t.Task}, t.Aliases...)
	for _, taskName := range names {
	candidateNames := append([]string{t.Task}, t.Aliases...)
	for _, taskName := range candidateNames {

Returning nil for both matching tasks and error when 'call' is nil might be ambiguous for API consumers; consider returning an explicit error or adding documentation to clarify this behavior.
