Set the Type radiobuttons in the Add Dictionary Entry dialog to be arranged vertically rather than horizontally

[SaschaCowley]

Link to issue number:

Temporary fix for #19657 

Summary of the issue:

The "Type" radio buttons in the "Add Dictionary Entry" dialog were displayed on a single line, causing the dialog to stretch off screen.

Description of user facing changes:

These radio buttons are now displayed in a single column rather than a single row.

Description of developer facing changes:

None

Description of development approach:

Set the radiobox's style to wx.RA_SPECIFY_ROWS. Also added a call to self.CentreOnParent to properly centre the dialog on its parent.

Testing strategy:

Ran from source and checked that the radio buttons were arranged vertically and the dialog was centred on the speech dictionary dialog.

Known issues with pull request:

This is a temporary fix, with the desired long-term fix being to convert to a combobox.
