feat: set component versions to 0.1.0-alpha

[jvallesm]

Because

• We need a way to introduce breaking changes in a sensible way.
• Component page will need the version and release stage of components.

This commit

• Adds a version field to the component definition. Initial version is
  0.1.0-alpha as we don't have a way to migrate components at the moment and
  thus we can't guarantee that we won't introduce more breaking changes.
• Moves each component package to a v0 directory so more than one major
  version can coexist.
• Introduces the source_url field in the component definition. This field is
  required by the component page and will be returned in the connector /
  operator definition list.

Notes

Adding the source_url field in the definition isn't great as it references a
particular branch (in the blob/main bit) and because writing it by hand
shouldn't be required. It would be great if we could just build it from the
component ID but several connectors (e.g. gcp or instill-model) don't match
the package and the ID. Also, there's no clean way to build this value and
inject it into the Load[Connector|Operator]Definitions function.

To make the definitions file easier to build and less error-prone, we should
introduce a linter and perhaps a boilerplate builder in the future.

🤖 Script to migrate to v0

#!/usr/bin/env bash

set -eo pipefail

# This script modifies the directory of each component and sets their version
# to 0.1.0-alpha. It automatically updates the references to that package.
#
# Usage: sh newversion.sh

for p in $(fd definitions.json | cut -d '/' -f1-2 | sort | uniq); do

  # Move component into v0 subdirectory
  mkdir v0
  mv $p/* v0
  mv v0 $p/v0

  # Update references
  escaped=$(echo $p | sed 's/\//\\\//g')
  grep -rl github.com/instill-ai/connector/$p | sort | uniq | xargs -I '{}' sed -i '' "s/\(github.com\/instill-ai\/connector\/$escaped\)/\1\/v0/g" {}

  # Add version and source URL to definition
  v=0.1.0-alpha
  url=github.com/instill-ai/connector/blob/main/$p/v0

  jq ".[0] += {version: \"$v\", source_url: \"$url\"}" $p/v0/config/definitions.json > def.json
  mv def.json $p/v0/config/definitions.json

done;
