Allow to select file to seed

[Kazimir42]

in some branch on dolibarr the seeder file isn't "mysqldump_dolibarr_%%BRANCHNAME%%.sql" like the develop branch who use the v17 seeder file "mysqldump_dolibarr_17.0.0.sql"

so --seed not working on branch develop for example

Yes indeed, what we can do is add a new variable.

DOLIBARR_MIGRATE_VERSION.

If this variable is set we will checkout the specific version and run the MySQL dump file.

For example we can specify to checkout 16.0 branch and run associated 16.0 seeder and then checkout back to $DOLIBARR_VERSION.
