Support for Opening Multiple SQL Files Simultaneously

[Zalan1995]

It would be highly beneficial if pgAdmin could support opening multiple SQL files at once in the Query Tool. Currently, users have to open each file individually, which can be time-consuming when working with several files. A feature allowing users to select and load multiple SQL files in separate tabs or within the same session would greatly enhance productivity, especially for those handling complex workflows or large projects.

Proposed Solution:

Add a "Multi-File Open" option in the Query Tool, allowing users to select multiple files simultaneously.
Each file could open in a separate tab automatically.
Alternatively, provide an option to combine the contents of selected files into a single tab.

Use Case:
For database administrators and developers who need to execute or edit several SQL scripts consecutively, this feature would save significant time and streamline the workflow.

Thank you for considering this feature request!

File dialogue should allow multiple file selection.(Similar to VS code)
