Bedrock (composer/installers): Composer 2 compatibility

[strarsis]

I just noticed that Trellis dropped prestissimo in favor of composer 2, however, the composer/installers package used by Bedrock wasn’t compatible with composer 2. A fix is now in master of composer/installers, but not released yet.
When composer/installers publishes a new release, Bedrock should be updated, so it works correctly with latest Trellis and composer 2.

@strarsis I was able to manually fix this by updating the composer.json file to use version 1.9 of composer/installers.

“composer/installers”: “^1.9”,

I released Bedrock 1.14.3 with this compatibility fix: https://github.com/roots/bedrock/releases/tag/1.14.3
