HPC-8663: add software info query

[manelcecs]

As described in HPC-8663 we needed a way to know wich version was deployed.
I've added a GraphQL resolver to query software info following this structure query
query { softwareInfo { title status version } }

I think it will be interesting to start adding test for GraphQL resolvers (now the project is on an early stage).
I can add the environment config (I thought of using ts-jest) but I don't know if it's suitable to add this in this PR or create a task where solve this situation.

Please make sure CI checks are passing and then assign the PR to person who you want review from.

Regarding the tests, I agree, we should add them sooner rather than later. Since we don't have test coverage here or in common library between our APIs (hpc-api-core), we have tickets to add test coverage and setup testing in both repos. Look at HPC-8232 and HPC-8233.

There is also an idea to run the tests in transactions (HPC-7811) rather than deleting entire tables all the time. With all of this in mind, a work has started long time ago at UN-OCHA/hpc-api-core#26 and parts of it could potentially be used, but I suggest starting from scratch.
