[BUG] Build.sh script failure

[derek-ho]

What is the bug?
After introducing a custom script to build security dashboards plugin, builds started failing with a different error than cypress version mismatch.
How can one reproduce the bug?

What is the expected behavior?
Builds successfully
What is your host/environment?

• OS: [e.g. iOS]
• Version [e.g. 22]
• Plugins

Do you have any screenshots?
No
Do you have any additional context?
It seems like the relative path is messed up, and would be different than the script being run in the build repo. After changing the relative path it should work.

[Triage] Marking as triaged. Please submit a PR with a fix once its determined what the path should be in the script.
