fix: Prevent trailing slash in example paths

[sentry]

This PR fixes an issue where navigating to an example index page (e.g., /query/latest/docs/framework/vue/examples) would result in a validation error. The params._splat parameter is empty in such cases, and the previous logic [framework, params._splat].join('/') would produce a path with a trailing slash (e.g., vue/). This trailing slash was then included in repoStartingDirPath (e.g., examples/vue/), causing isValidRepoPath to fail.

The fix involves adding .filter(Boolean) to the array before joining the path segments, ensuring that empty strings (from an empty _splat) are removed. This prevents the generation of trailing slashes in the examplePath and repoStartingDirPath, resolving the validation error.

Changes made in src/routes/_library/$libraryId/$version.docs.framework.$framework.examples.$.tsx:

• Updated [framework, params._splat].join('/') to [framework, params._splat].filter(Boolean).join('/') in three locations to correctly construct examplePath without trailing slashes when _splat is empty.
