Fixed typo that gives error while building

[PaulSimode]

There seems to be a typing error in helpers/index.ts, line 17.

I believe the correct path is "../tasks/market-registry/market-registry_add" instead of "../tasks/market-registry/market-registry:add". Changing this allowed me to continue with building.

The corresponding issue is #49.

Link Height tasks by mentioning a task ID in the pull request title or commit messages, or description and comments with the keyword link (e.g. "Link T-123").

💡Tip: You can also use "Close T-X" to automatically close a task when the pull request is merged.

The file it's actually named market-registry:add. However, will rename to market-registry-add for consistency. Thanks @PaulSimode
Done in #51
