Call Yarn Command From Corepack Command in Workflow

[threeal]

This issue proposes a modification to our workflow by replacing direct yarn ... commands with corepack yarn .... The rationale behind this adjustment is that the default Yarn version installed on the GitHub Action runner may be outdated compared to the version used in this project. To address this, we utilize corepack enable yarn to ensure compatibility. It appears that yarn commands can be executed through corepack yarn to explicitly indicate the usage of Yarn enabled by Corepack. This change aims to prevent inadvertent use of the potentially outdated Yarn version on the GitHub Action runner and encourages a more reliable and consistent workflow.
