3rd party URLs dialog should not wrap text

[kittaakos]

Describe the problem

IDE 1.x does not wrap the URLs. IDE2 does. It should not.

IDE2:

3rd_party_ide2.mp4

IDE 1.x:

3rd_party_ide1x.mp4

To reproduce

Use the following 3rd party URLs:

http://digistump.com/package_digistump_index.json,http://www.leonardomiliani.com/repository/package_leonardomiliani.com_index.json,https://ambasat.com/boards/package_ambasat-1.com_index.json,https://arduino.esp8266.com/stable/package_esp8266com_index.json,https://dl.espressif.com/dl/package_esp32_index.json,https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json,https://mcudude.github.io/MightyCore/package_MCUdude_MightyCore_index.json,https://rabidprototypes.com/arduino/package_rabidprototypes_index.json,https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json,https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json,https://resource.heltec.cn/download/package_CubeCell_index.json,https://resource.heltec.cn/download/package_heltec_esp32_index.json,https://resource.heltec.cn/download/package_heltec_esp8266_index.json,https://raw.githubusercontent.com/SpenceKonde/ReleaseScripts/master/package_drazzy.com_index.json

Enter the URLs via the Settings dialog. Each URL should be in a new line without text wrap.

Expected behavior

Like in IDE 1.x. See the description.
