Fix: Correct spacing in EXPERIMENTAL label in README.md

[myeunee]

Description

This pull request updates the README.md file to correct the spacing in the EXPERIMENTAL label within the "TLS endpoint" section. The previous version had extra spaces around the word, which have been removed for consistency.

Motivation

The term EXPERIMENTAL was previously formatted with extra spaces (** EXPERIMENTAL **), which was inconsistent with the rest of the document's formatting. Removing the extra spaces improves the readability and consistency of the documentation.

Changes Made

• Updated the README.md file to change ** EXPERIMENTAL ** to EXPERIMENTAL.
