chore(config, docs): Replace 'vector.toml' with 'vector.yaml' (#18388)

* chore(config, docs): Replace 'vector.toml' with 'vector.yaml'

* keep both vector.toml and vector.yaml

* remove vector.toml from asserts, still attempt to load it first and finally fallback to vector.yaml

* update conf-files and docs as well

* clippy fixes

* Update src/cli.rs

Co-authored-by: Jesse Szwedko <jesse.szwedko@datadoghq.com>

* Update src/config/cmd.rs

Co-authored-by: Jesse Szwedko <jesse.szwedko@datadoghq.com>

* address Jesse's review points

* add 'pront' to dictionary

* small fixes

* remove conf-files

+#### Default config location change {#default-config-location-change}
+
+The default config location `/etc/vector/vector.toml` which is used by Vector `0.32.0` is now deprecated. This location will still be used in `0.33.0`. The new default path is `/etc/vector/vector.yaml`, please migrate to this new default path or specify the config path explicitly.

+Vector `0.33.0` will attempt to load `/etc/vector/vector.toml` first, and if it is not present, it will fallback to `/etc/vector/vector.yaml`. However, Vector release `0.34.0` will automatically load `/etc/vector/vector.yaml` only.
