Add a default 1000 user in dockers

[fbeutin-ledger]

Before:

$> docker run -it ghcr.io/ledgerhq/ledger-app-builder/ledger-app-builder:latest
root@eea4e3a49139:/app# whoami
root

After

$> docker run -it ledger-app-builder:local
base_user@22215901ecec:~$ whoami
base_user

This gives the default 1000 user a home dir which enables seamless auto VSCode DevContainer integration

@fbeutin-ledger no side effect to change the user from root to the base user in some CI workflows or stuff like that ?

@yogh333 do we still need https://github.com/LedgerHQ/ledger-vscode-extension/blob/03ebf1d1a12cf9644657c6a7a0878b8c4407b906/src/containerManager.ts#L10 after this PR is merged ? 🤔

For windows we still need to change the user to root at least I guess
