fix(docs): Prevent trailing slash in example path from causing validation error

[sentry]

This PR fixes an issue where navigating to an examples index URL (e.g., /table/v8/docs/framework/react/examples) would result in a validation error.

The root cause was that when the _splat parameter was empty (indicating the examples index), the path construction [framework, params._splat].join('/') would produce a trailing slash (e.g., "react/"). This trailing slash then caused the repoPathSchema validator in fetchRepoDirectoryContents to reject the path, leading to the observed error.

The fix involves adding .filter(Boolean) to the path construction:
[framework, params._splat].filter(Boolean).join('/')

This ensures that empty segments (like an empty _splat) are filtered out before joining, preventing the creation of a trailing slash and allowing the path to pass validation.

The source audit found that this duplicates #1197. Both fix the same loader expression and reported validation failure, while #1197 also normalizes the two remaining example paths used by deploy and repository links. I recommend closing this one and reviewing #1197 so only one coherent fix lands.
