[Grid Editor] Cell edit with `F2` hotkey is not working

[ZDabrowski]

Cannot enter the edit mode of the cell when the F2 hotkey is pressed, Additionally, when F2 is pressed on a non-empty cell and then on the empty cell, the content will be pasted.

Environment Python 3.10.12 wxPython 4.2.1 robotframework 6.0.2 robotframework-ride 2.1.dev70 Ubuntu 22.04.4 LTS

Steps

1. Enter some content into cells
2. Press F2 to enter edition mode (cell content blinked for a while, but did not enter edition mode)
3. Move cursor to the other, empty cell and press F2 (cell filled with the content of previously selected cell)
4. Move cursor to the cell with content and press F2
5. Move cursor to the empty cells and press F2

Additional info Did not notice F2 shortcut key description in the Help->Shorcut keys->Grid Double-click is working properly.
