SSR-4650: Resolve critical security alert

[huuchi1778]

Background
This is the resolution for a critical Dependabot alert related to the @babel/traverse package used by @babel/core and its dependencies. As described in the Vulnerability details, upgrading @babel/core to a version >=7.23.2 will automatically pull in a non-vulnerable version of @babel/traverse.

Detail of Action

• Changed the version of @babel/core used by kintone-cli from 7.22.15 to 7.24.5 (latest)
• Changed the version of @babel/core in the template file used by apps created by kintone-cli from 7.22.9 to 7.24.5 (latest)

----- Additional Implementation -----
[Reason]
Following the review comment

[Detail of Action]

• Updated all packages under the @babel namespace to the latest v7.24.6 in the kintone-cli source and the template files
• Removed the unused @babel/plugin-syntax-dynamic-import because @babel/core >= 7.8.0 does not need it anymore (https://babeljs.io/docs/babel-plugin-syntax-dynamic-import)
• Replaced the deprecated @babel/plugin-proposal-class-properties by @babel/plugin-transform-class-properties (https://www.npmjs.com/package/@babel/plugin-proposal-class-properties)
