feat: Unpublish rollbar_{dart,flutter} and add vendoring instructions

Since Rollbar will no longer be publishing package updates to pub.dev, it
will be helpful for many users to "vendor" the Rollbar packages into their
projects so that they can have full control over package versions, pull in
fixes from the community, etc. For example, the rollbar_dart package on
pub.dev currently has an old http dependency, even though this has already
been updated on the main branch.

Add instructions to the README for vendoring rollbar_flutter into a user
project, and change the internal rollbar_{dart,flutter} dependencies to be
"path" dependencies (pulling from within this repo) rather than
"hosted" (pulling from pub.dev).

Fixes #124

+## Vendoring
+
+Since Rollbar will no longer be publishing package updates to pub.dev, it's
+recommended that you "vendor" the Rollbar packages into your project so
+that you can have full control over package versions, pull in fixes from
+the community, etc. For example, the `rollbar_dart` package on pub.dev
+currently has an old `http` dependency, even though this has already been
+updated on the `main` branch.
+
+To vendor this package in your project, it's recommended to add it as a
+`git` submodule. Typically you'll want to fork the repo so that you can
+make changes there, and use your fork for the submodule URL, like so:
+
+```
+git submodule add https://github.com/<YOUR_USERNAME>/rollbar-flutter.git vendor/rollbar-flutter
+```
+
+Next, remove `rollbar_flutter: ^X.X.X` from the `dependencies:` block in
+your `pubspec.yaml`, and add the following:
+
+```yaml
+dependencies:
+  ...
+
+  # vendored packages
+  rollbar_flutter:
+    path: vendor/rollbar-flutter/rollbar_flutter
+```
