Need to migration `node-sass` to `dart-sass`

[digitalisx]

Describe the bug Hello, everyone in the community! 🙂 We can see that node-sass is used as DevDependencies at the frontend of Timesketch.

https://github.com/google/timesketch/blob/172b2cac2e05efa30c26909365bdfb1083d25f64/timesketch/frontend/package.json#L53

However, it is recommended that the module is deprecated and that the community be migrated to dart-sass. These modules rely on older Python2 and related modules. This may not be a problem for immediate use, but can increase the complexity of using software in environments that no longer support Python2 by default. These issues will reduce the motivation of users, developers, and contributors alike.

To Reproduce This issue can occur when installing components inside the frontend folder.

> yarn install

Expected behavior Simplify installation for users and developers with diverse and up-to-date environments
