v2BotLocaleId does not support Lex V2 multi-locale bots IDs

[AbdulQayyumaq]

v2BotLocaleId in lex-web-ui-loader-config.json does not work correctly with Amazon Lex V2 bots that have multiple locales enabled.

• Passing an array of locales (e.g. ["en_US","fr_CA","ar_AR"]) fails immediately with a validation error.
• Passing a single string works only for one locale.
• Passing a comma-separated string (e.g."en_US","fr_CA","ar_AR") allows initialization but fails at runtime with a Lex V2 validation exception.

This makes it impossible to use multi-locale Lex V2 bots with aws-lex-web-ui.

Actual Behavior

• Array input → blocked by validation (only use string)

• Comma-separated string → runtime error:
  ValidationException: Value "en_US","fr_CA","ar_AR" at 'localeId'
  failed to satisfy constraint:
  Member must satisfy regular expression pattern:
  ([a-z]{2}[A-Z]{2}|[a-z]{2}[A-Z]{2}_[0-9]{3})$

• Chatbot fails to load and eventually times out.

It should not be an array it should just be a comma separated string...

"v2BotLocaleId": "en_US,es_US,fr_CA",

Hi, sorry, I see you edited your initial question so I did not see this update. Are you putting each value in its own string if so it should just be one string "en_US,es_US,fr_CA" not "en_US","es_US","fr_CA"
