Updates Lucene.Net.CodeAnalysis.Dev analyzer package to latest version, fixes some analysis warnings.

Description

This updates the Lucene.Net.CodeAnalysis.Dev package to alpha 36. See the release notes for alpha 34 and alpha 36:
https://github.com/apache/lucenenet-codeanalysis-dev/releases/tag/v1.0.0-alpha.34
https://github.com/apache/lucenenet-codeanalysis-dev/releases/tag/v1.0.0-alpha.36

This update adds several new analyzers. The dictionary ones (1007-1008) and numeric formatting ones (2000-2007) were very noisy with several thousand combined warnings, so they have been suppressed with NoWarn except for a couple that had just a few findings and were easy to fix.

The remaining findings should be addressed as separate PRs.

Pull request overview

Updates the Lucene.Net.CodeAnalysis.Dev analyzer package and adjusts the codebase to satisfy (or suppress) new analyzer findings, primarily around culture-safe string operations and span comparison APIs.

Changes:

• Bumped Lucene.Net.CodeAnalysis.Dev dependency to 1.0.0-alpha.36.
• Added solution-wide NoWarn suppressions for newly introduced/noisy analyzer IDs (dictionary indexer + numeric formatting rules).
• Fixed a handful of new diagnostics by explicitly specifying StringComparison on string APIs and simplifying span StartsWith/EndsWith calls.
