Task/upgrade yarn

[jmetev1]

1. upgrades yarn.
   i've been working on this for a while so not positive what will be required when others work in web/.
   Running yarn install might work. or may have to first do corepack enable yarn set version berry
   current npmrc might work. or might have to do

 yarn config set npmScopes.psu.npmRegistryServer https://artifacts.developer.gov.bc.ca/artifactory/api/npm/pe1e-psu-npm-local/
 yarn config set npmScopes.psu.npmAlwaysAuth true 
 yarn config set npmScopes.psu.npmAuthToken ${ARTIFACTORY_SVCACCT_TOKEN}

2. reorders dockerfile.web steps for better caching
