docs: Update base path for craft.sentry.dev domain (#734)

## Summary

The docs site has moved from \`getsentry.github.io/craft\` to
\`craft.sentry.dev\`. This caused assets to fail loading as they were
still being served from \`/craft/\`.

## Changes

- Change default base path from \`/craft\` to \`/\`
- Update site URL to \`https://craft.sentry.dev\`

PR previews continue to work via \`DOCS_BASE_PATH\` environment variable
override in the workflow.
