lib list and lib examples use incorrect library name

[per1234]

Bug Report

The name of an Arduino library is defined by the name property of its library.properties metadata file.

This is the sole unique identifier for the library, which is used in the LIBRARY_NAME argument of the arduino-cli lib commands. However, two of the commands instead use the library's folder name for the library name instead of its real name.

Current behavior

The following demonstration uses the "Arduino SigFox for MKRFox1200" library, the name of which is defined here:
https://github.com/arduino-libraries/SigFox/blob/1.0.4/library.properties#L1

name=Arduino SigFox for MKRFox1200

This library was selected because the spaces in the name cause the "normalized" Library Manager installation folder name (Arduino_SigFox_for_MKRFox1200) to be different from the library name.

$ arduino-cli lib examples "Arduino SigFox for MKRFox1200"
No libraries found.

Notice that in all cases except lib list and lib examples, the library name is "Arduino SigFox for MKRFox1200", while that correct name is not recognized when used in the library name argument of the final two commands.

Expected behavior

Libraries are always referred to by the correct name, consistently from one command to another.

Environment

• CLI version: nightly-20211201 Commit: 55ad9ec Date: 2021-12-01T01:29:21Z
• OS and platform: Windows 10

Additional context

There is one case where the library folder name determines the library name: the "1.0 format" or "legacy" libraries that do not have a library.properties metadata file:

https://arduino.github.io/arduino-cli/dev/library-specification/#old-library-format-pre-15

---

The name field value is sometimes referred to as the "real name" or "fancy name".
