Bump/nodejs v18

[RodriSanchez1]

On this PR:

• Node version was updated to v18.18.1. The new version was pinned on docker file, .nvmrc and CI config.
• React-scripts package was updated to v5. This changes comes with an upgrade of Webpack to v5. To make all works properly, the CRACO package was added for config webpack avoiding to eject.
  NOTE: We are currently react-rewire (similiar than CRACO) but is not maintened anymore. Needs to migrate.
• Change option --maxWorkers=50% for --runInBand on CI config. This change was made because the Unit Test were hanging with no output response. Also increment the run speed of the test.
• Fix default export on Import.constants.js and Export.helpers.js
• Ignore url webpack resolution on WelcomeScreen.css
• Fix openDb import on arasaac.ts
• Update yarn.lock file

No, we still use it. But an update to react-scripts was needed to support Node v18.
I'm planning to migrate to Vite and then we can remove it.

Do you change your node version to v18.18.1 before build? On my pc is building well.

is react-app-rewired needed? can you use craco instead? (i'm not sure)

[RodriSanchez1]

Yes we can remove it. I will do that in other PR
