Lock the terraform version

[dadiorchen]

As we metioned here: https://greenstand.slack.com/archives/CH79F6W8G/p1699325772739259 the terraform version matters, so we need to find a way to lock the version in case people accidentally run terraform in the wrong version, specially for the db grant : https://github.com/Greenstand/treetracker-infrastructure/tree/master/database-grants/terraform

perhaps required_version can be used in terraform provider block, from the terraform state file found in the digital ocean object storage the last applied version is: "terraform_version": "1.4.6",

@sanketnadkarni sounds good, can you try it and give me the report? by adding that setting

[sanketnadkarni]

I will try it this week and confirm.

@dadiorchen please have a look at the following PR: #233
I have implemented this for the dev environment for database-grants , we can discuss further in the PR and once approved we'll merge this and replicate the same for other envs.

Could you also help me to link this issue to the PR.

Thanks.
