Fix compilation database command for CLion page.

**Your Godot version:** 4.x, I`m not sure if this applies to 3.x

**Issue description:** The Clion documentation page's **Importing the project** section instructs to generate a compilation database with `scons compiledb=yes`, and then the next section compiles the engine normally with `scons`, however, running that first command also compiles the engine. I think this should be consistent, either by correcting the command to `scons compiledb=yes compile_commands.json` (doesn't compile the engine) in the first section, or just linking the compilation database instructions to the **Configuring an IDE** section, which describes both commands.
