Filename autocompletion for dot program does not accept .gv extension

[bluelightning32]

Describe the bug

Dot is a program in the graphviz package. Its source files used to use .dot as a file extension. However, according to wikipedia, .gv is now the preferred file extension.

Bash autocompletion only accepts files with the legacy .dot extension. It will not autocomplete files with the .gv extension.

To reproduce

1. Create a blank file called test.gv. For example, it can be created by running : >test.gv.
2. Type dot test.
3. Hit tab. Watch how the filename is not completed.

Expected behavior

The test.gv filename from the example should be expanded when tab is pressed.

Versions (please complete the following information)

• Distro: Fedora Linux 39
• bash version: 5.2.26(1)-release
• bash-completion version: 2.11
