chore: switch to libs.versions.toml file and add dependabot

[buenaflor]

#skip-changelog

Move over most dependencies to the toml file and add dependabot - I have kept the original versions, I will update them in the PRs created by dependabot

I'm not changing the sentry cocoa & android sdk yet since our bot updater updates the config.kt file, we'd have to change that at some point to update the toml file
