Rebuild templating using Go text templates

Seeking to resolve the CI disparity between ecosystem managed repositories and pulumi/pulumi-std#29, it quickly became apparent that the style of GitHub Actions - using reusable workflows - in that repository and in pulumi-command would require a major rewrite of the templating in this repository.

Making large changes to the templating in this repository is more difficult as it requires modifying the Node scripts and the type-safe "generator" to reverse engineer CI workflows into a known form.

Directly generating text templates, we skip the intermediate steps and can more naturally write the intended GitHub Actions YAML.

The Go utility in this repository can be run and a diff with the current repository scripts generated via:

cd ./package-ci
./scripts/test.sh

The committed template, "bridged-provider", is intended to be bit-for-bit identical in output to the current scripts to the extent possible. As a result, there is no semantic diff with the current output.

The two cases where the output was not identical are in the New Relic provider, and the diff is inconsequential wrapping behavior in the current Node scripts that is not present in the Go text template, both appearing in .goreleaser files. In this case, the wrapping has no effect on Goreleaser:

I like moving from custom generation code to go templates. What's the plan for rolling this out? I'm assuming we keep the old behavior (and all the old code) for team providers?

Will we flip a switch somewhere to make sure that we only build our team's actions with the new generator?

I'm in favor, the devil though is in ensuring uneventful rollout. If the new system still materializes all the workflow files and there's a zero diff (it's byte-for-byte the same) then it'd be excellent we can just swap the generator out without projects noticing.

This commit deletes the provider CI folder and replaces it with
package-ci, applying #446, updating the Makefile to conform to the same interface.

Two shared TypeScript files are moved to native-provider-ci:
* provider-ci/src/shared-workflows.ts
* provider-ci/src/action-versions.ts

Builds on #446 and #450 by adding linting.

The Makefile is updated to make for a fast inner dev loop on changing templates.
Using a tool such as `watchexec`, we can run:

```sh
watchexec -i providers -- NAME=databricks make lint-provider
```

When running in a loop like this, `watchexec` should trigger on changes to
templates, rebuild `bin/provider-ci`, and regenerate the output. When changing
config files, the `provider-ci` binary should remain unchanged:

```
$ make bin/provider-ci
make: 'bin/provider-ci' is up to date.
```

The `provider` and `providers` targets now run linting by default.

Since @kpitzen and team cleared this change, let's do it.

Do we want to include instructions for running the /scripts/test.sh as part of development? Or should we remove it, as it was part of the PoC?
