Copied instruction inherits later changes to original instruction

Current Situation:

• When an instruction is copied and is modified later on, the pasted instruction adopts modifications to the original instruction rather than remaining the version that was initially copied.

Steps to reproduce:

• Create a workflow w1 and add a block instruction.
• Add a job in the block instruction.
• Copy the block instruction and paste it into the same workflow
• Now modify the original block instruction by adding another job.
• Paste the block instruction in the same workflow the pasted block instruction will now contain two jobs.

Desired Behaviour:

• The copied instruction should remain in its original configuration (as it was when copied), regardless of any changes made to the original block afterward.
