Ci improve ci time iteration 3

[belgattitude]

Follow up to second iteration > 45%. Now trying to reach > 55% workflow speed-up.

Warning: the only changed file is the lock, will be more apparent when parent branch is merged: #16638

In this iteration I'm trying to get rid of semver compatible duplicates (across transitive deps).

More info to come, but in general

• the current lock have 333 duplicates.
• meaning we install a lot of dependencies that might be redundant (ie: tslib in 6 different versions)

To see that just run

yarn dedupe --check

on master.

In my experience dealing with multiple versions leads to more complex bugs than the risk of having a bc sometimes (the nodejs ecosystem seems to be more and more strict regarding bc). Anyway upgrades will happen

This iteration is more risky of course. But as the CI is very good why not trying ?

BTW: it might have a very nice side effect on the build size as well. I'll measure

PS: Adding also a note about dependabot vs renovate bot...

If the deduplication works I can help moving to renovatebot (supports deduplication from the config file and much more interesting features like grouping), ie:

{
  "extends": ["config:base"],
  "enabled": true,
  "enabledManagers": ["npm", "docker-compose", "dockerfile", "github-actions"],
  "postUpdateOptions": [
    // https://docs.renovatebot.com/configuration-options/#postupdateoptions
    // Will run yarn dedupe --strategy highest
    'yarnDedupeHighest'
  ],

I'll P/R in a next iteration

Closing in favour of #16764.
