Describe the bug

Library authors provide information about the library in the library.properties metadata file. This is displayed in Library Manager. The classic Arduino IDE has some support for formatting text using HTML, which is used by a significant number of libraries.

🐛 Arduino IDE 2.x Library Manager does not have HTML support, exposing the raw markup to the viewer.

To Reproduce

1. Open Library Manager in the Arduino IDE.
2. Search for the official "Servo by Michael Margolis, Arduino" library.

🐛 Note that the description of the library contains multiple <br />.

🐛 Note also that multiple nearby 3rd party libraries in the search results (e.g., "Servo Hardware PWM by Daniel Duller", "Servo Easing by Armin Joachimsmeyer", "SoftPWM by Brett Hagman", "XLR8RC by Alorium Technology") also use HTML, which gives some statistical idea of how widespread the practice is in the 4k+ Library Manager libraries.

Expected behavior

Support basic HTML for library descriptions.
