docs: Fix a few typos (#6878)

There are small typos in:
- closure/goog/base.js
- demos/minimap/minimap.js
- gulpfile.js
- scripts/gulpfiles/build_tasks.js
- scripts/gulpfiles/cleanup_tasks.js
- scripts/gulpfiles/license_tasks.js

Fixes:
- Should read `prerequisites` rather than `prequisites`.
- Should read `satisfies` rather than `satisifies`.
- Should read `regenerates` rather than `regenrates`.
- Should read `minimap` rather than `mimimap`.
- Should read `diagnostic` rather than `disagnostic`.
