FIX: Change the values of the files generated by bst init when type e2e and multi locale.

[maxbespoken]

Only when the type is e2e and it is a multi-locale project the project created should be created with the following file:

index.e2e.yml

---
configuration:
  description: $testSuiteDescription
---
- test : $firstTestName
- $INVOCATION_UTTERANCE : "$launchPrompt"
- $HELP_UTTERANCE : "$helpPrompt"

en-US.yml

$testSuiteDescription: My first unit test suite
$firstTestName: Launch and ask for help
$launchPrompt: okay here's
$helpPrompt: What can I help you with?
$INVOCATION_UTTERANCE: Open voice hello world overview
$HELP_UTTERANCE: help
