Is your feature request related to a problem? Please describe.
OpenMetadata currently supports multiple languages in the UI (English, French, Chinese, Japanese, etc.) but lacks comprehensive Russian language support for Elasticsearch search indexing. Russian-speaking users experience poor search quality because:

• No Russian-specific analyzers configured in Elasticsearch mappings
• Russian text is processed using generic English analyzers
• Cyrillic characters and Russian morphology are not properly handled
• Search results are less relevant for Russian queries due to improper tokenization and stemming

Describe the solution you'd like
Implement comprehensive Russian language support for Elasticsearch

Describe alternatives you've considered

• Using existing English analyzers: Poor quality for Russian text
• Manual configuration: Too complex for end users

Additional context
This feature request aims to provide the same level of search quality for Russian users as currently available for English, Japanese, and Chinese languages. The implementation should include enhanced analyzers that are potentially more comprehensive than the basic English configuration.
