Update Dependencies and add Renovate/Dependabot

Problems with Existing Functionality

The latest release is 2 years old

[dependencies]
rocket = { version = "0.5.1", default-features = false, features = [
  "http2",
  "json",
  "uuid"
] }
rocket_db_pools = { version = "0.2.0", default-features = false, features = [
  "sqlx_mysql",
  "sqlx_postgres",
  "sqlx_sqlite"
] }

and in the future rust version, some of the dependencies of rocket will break, even though they have fixed it upstream.

Suggested Changes

Update the Dependencies to newer versions.
Rust is extremely stable and reliable, but still software ages (

• humans make errors, sometimes even in rust
• specifications change (like in this case with the new rust version that will come)
• fundamental design flaws are found, that make a system insecure (those patches should get rolled out fast)
  ).
  This is true for every project, so it affects Rocket and all its dependencies.

so adding dependency management with Renovate or Dependabot, will allow for small incremental dependency updates, that can be easily checked by CI, so if something breaks in one of those incremental dependency update MRs, its often much easier to identify, than if you Mass update, and multiple breackages happen at once.

System Checks

• I do not believe that this suggestion can or should be implemented outside of Rocket.

• I was unable to find a previous suggestion for this change.

I am working on a fork as I have had no real feedback with the current owner.

Is early days, but I hope to have all the mechanics up and running for a first RC for a v1 in a couple of weeks. But happy for any input.

im currently looking into actix to be honest, as the sice of a comunity matters.
still im sad, that its also on github and not codeberg...
Microsoft clearly showed that they don't care about devs...
