Add Tagging Verification Feature to verifications Branch

[NabilMx99]

This pull request introduces a new feature to the verifications branch that adds tagging verification functionality for
the tag-it exercise. The feature includes the following changes:

New Exercise tag-it

• A new exercise, tag-it, has been added to the repository. This exercise is designed to help users practice creating and verifying Git tags. See New Exercise: tag-it #67

• The exercise requires users to create two commits and associate them with specific tags (v0.1.0 and v0.2.0).

Verification Logic

• The exercise verification logic has been implemented in the TagIt.php file.

• The verification ensures:

  • Two commits are present in the branch.
  • The correct file App/src/Program.cs is modified in both commits.
  • Each commit has exactly one tag associated with it.
  • The tags v0.1.0 & v0.2.0 are correctly associated with the respective commits.

Updates to start.sh script

• The start.sh script initializes the exercise environment by creating the first commit and tag v0.1.0 and setting up the environment for the user to create the second commit and tag v0.2.0. See New Exercise: tag-it #67

Other changes

• Minor update to the git verify alias command to support tag pushes for exercise verification. See Enhance git verify alias to support tag pushes for exercise verification #66

⚠️ Tagging Verification Issue

While testing the tag-it exercise, I encountered an issue where the git verify command fails with the following error:

After thorough investigation, I identified that the root cause of this issue is that the tag-it branch exists in my fork but does not exist in the original repository. The server-side hook in the original repository validates the branch name against a predefined list of valid exercises. Since the tag-it branch is not present in the original repository, the hook rejects the push and does not process the tags.

I kindly request that you review this pull request, create a branch named tag-it, and merge the changes into it. This will allow the exercise to be recognized as a valid exercise by the server-side hook, resolving the verification issue.
