Thanks for catching this @emrahcom.
Can you make the same changes for /docs/docs/quickstart.mdx as well, please?

Thank you very much for your contribution to the documentation! Due to the way Docusaurus versioning works, you need to make the changes in two locations:

• docs/versioned_docs/version-v{version}/path/to/file
• docs/docs/path/to/file

Without making them in both locations, the changes will most likely be lost when releasing another version. Thank you! :)
