Title

doc: clarify Web Storage behavior and document --localstorage-file option

Description

### Issue Resolved
This pull request addresses the issue outlined in [#53871](https://github.com/nodejs/node/issues/53871). The changes clarify the Web Storage behavior in Node.js and document the `--localstorage-file` option.

### Changes Made
1. **cli.md**: Added documentation for the `--localstorage-file` option.
   - Placed after the `--max-old-space-size` section.
   - Described how to use the `--localstorage-file` option to specify the file used for `localStorage` in Node.js.
   - Mentioned key considerations such as the possibility of concurrent access by multiple processes and the 10MB storage quota per process.

   Example documentation snippet added:
   ```markdown
   ### --localstorage-file

   The `--localstorage-file` option specifies the file used for `localStorage` in Node.js.

   - This file can be accessed by multiple processes simultaneously, which might require implementing file locking or other synchronization mechanisms to ensure data integrity.
   - The storage quota for `localStorage` is 10MB per process.

2. globals.md: Added a new section describing how localStorage and sessionStorage behave in Node.js.

   • Clarified that both are scoped to the current process.
   • Explained that the --localstorage-file flag determines the file used for localStorage.
   • Reiterated the 10MB per process storage quota.

   Example documentation snippet added:

   ## Web Storage API
   
   In Node.js, the `localStorage` and `sessionStorage` objects function differently compared to browsers or Deno:
   
   - Both `localStorage` and `sessionStorage` are scoped to the current process, not individual users or server requests. This is crucial for applications like server-side rendering.
   - `localStorage` uses the value of the `--localstorage-file` flag as its origin. This file can be accessed simultaneously by multiple processes, which may require implementing file locking or other synchronization mechanisms to ensure data integrity.
   - The storage quota for both `localStorage` and `sessionStorage` is 10MB per process.

Note

• The --localstorage-file option is currently documented but not implemented in the Node.js core. Therefore, the added documentation is primarily for reference and future-proofing.
• No new tests have been included, as this PR only addresses documentation changes. -- I feel that my contributions are still lacking, and I appreciate any feedback you may have to help me improve. Thank you for your understanding:)
