Fix readme txt version (#5200)

* chore(re-version.sh): update sed command to replace "release-SNAPSHOT" with the current version in .txt files

The sed command in the re-version.sh script is updated to replace "release-SNAPSHOT" with the current version in .txt files. This ensures that the version information is correctly updated in the files during the re-versioning process.

* fix(re-version.sh): remove duplicate sed command to improve efficiency and readability
