Use of version_lt function instead of less than (eclipse-che#5141)

less_than is not working with for example “5.9.1” and “5.10.0”, 5.9.0 being said to be a greater version

bash-4.3# version_lt "5.9.0" "5.10.1"
—> 0

bash-4.3# less_than "5.9.0" "5.10.1"
—> 1

bash-4.3# less_than "5.6" "5.8"
—> 0

note: version_lt is a less and equals method, so we need to exclude the condition : tag == base version
