Contents of text input fields are spell checked

[LightningStalker]

Describe the problem

The following text input fields are spell checked:

• File > Preferences > Sketchbook location
• File > Preferences > Additional Boards Manager URLs
• Filter your search... field of Library Manager view.
• Filter your search... field of Boards Manager view.
• Search board field of "Select Other Board & Port" dialog.
• "message" field of Serial Monitor

This is really not appropriate or useful for the type of data that will be input via any of these fields.

There isn't any context to explain what the meaning is of the red underline, so it is likely to make beginners think they are doing something wrong. It also harms readability.

To reproduce

1. Open the board selector menu on the Arduino IDE toolbar.
2. Select "Select other board and port..." from the menu.
3. Type leonardo in the "Search board" field.
4. Wait a few seconds.

🐛 A red underline appears under the search text:

Expected behavior

Do not spell check these fields.
