[MAINT] Update issue templates

[ViacheslavKudinov]

This pull request updates the GitHub issue templates to improve clarity, collect more relevant information, and streamline the reporting process. The most significant changes include adding a required "GitHub Installation Type" field to several templates, removing unused SDK/API version fields, and refining instructions to help users provide better context and redact sensitive information.

Enhancements to information collection:

• Added a required "GitHub Installation Type" checkbox field to the bug and feature request templates, allowing users to specify their GitHub environment (Cloud, Enterprise, etc.), which will help triage and diagnose issues more effectively. (.github/ISSUE_TEMPLATE/bug.yml, .github/ISSUE_TEMPLATE/feature.yml) [1] [2]
• Removed optional SDK and API version input fields from the documentation, feature, and maintenance templates to simplify the forms and focus on more actionable information. (.github/ISSUE_TEMPLATE/documentation.yml, .github/ISSUE_TEMPLATE/feature.yml, .github/ISSUE_TEMPLATE/maintenance.yml) [1] [2] [3]

Improvements to user instructions and template clarity:

• Updated instructions and placeholders throughout the bug template to encourage redacting sensitive information, clarify what configuration details are needed (including module context), and request additional context for reproducing issues. (.github/ISSUE_TEMPLATE/bug.yml) [1] [2] [3]
• Revised the debug output section in the bug template to explicitly request logs generated with TF_LOG=DEBUG and remind users to redact sensitive data. (.github/ISSUE_TEMPLATE/bug.yml)

General template maintenance:

• Added minor formatting improvements and whitespace consistency across all templates for better readability. (.github/ISSUE_TEMPLATE/documentation.yml, .github/ISSUE_TEMPLATE/feature.yml, .github/ISSUE_TEMPLATE/maintenance.yml) [1] [2] [3]
• Ensured all templates include a terms and conditions checkbox for user acknowledgment. (.github/ISSUE_TEMPLATE/documentation.yml, .github/ISSUE_TEMPLATE/feature.yml, .github/ISSUE_TEMPLATE/maintenance.yml) [1] [2] [3]
