Fix typos and improve documentation clarity

[Dahka2321]

Changes Made

File: src/plugins/projectGalaxy/README.md

1. incentive → incentivize

   • Reason: "Incentivize" is the correct verb form to express encouraging or motivating behavior, while "incentive" is a noun.

2. campain → campaign (in JSON examples)

   • Reason: Corrected spelling of "campaign" which is the standard English spelling for this word. This ensures proper functionality as incorrect spelling could cause implementation issues.

File: src/plugins/progress/readme.md

1. Authetication → Authentication

   • Reason: Fixed the spelling of "Authentication" which is the correct technical term for web3 identity verification.

2. notificatiosn → notifications

   • Reason: Corrected typographical error in the word "notifications" to improve readability and professionalism of the documentation.
