The `sketch new` command ignores the sketch folder name specification

[kittaakos]

Describe the problem

I can use the CLI sketch new to create invalid sketches which will not compile. The little sister task of this one is arduino/arduino-ide#1599.

To reproduce

./arduino-cli version                                                          
arduino-cli  Version: git-snapshot Commit: a58d5adb Date: 2023-01-23T09:37:23Z

./arduino-cli sketch new "/Users/a.kitta/Documents/Arduino/\`~%^&()=+[{]};',.cpp"
Sketch created in: /Users/a.kitta/Documents/Arduino/`~%^&()=+[{]};',.cpp

cat ~/Documents/Arduino/\`\~%\^\&\(\)=+\[\{\]\}\;\',.cpp/\`\~%\^\&\(\)=+\[\{\]\}\;\',.cpp.ino

void setup() {
}

void loop() {
}

./arduino-cli compile -b arduino:avr:uno  "/Users/a.kitta/Documents/Arduino/\`~%^&()=+[{]};',.cpp"

Expected behavior

new sketch fails when the sketch's name is invalid. https://arduino.github.io/arduino-cli/dev/sketch-specification/#sketch-root-folder

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the nightly build
• My report contains all necessary details

This should be a matter of implementing a regex to check if the sketch name is a valid one

[umbynos]

AC: if a name that does not respect the regex is used an appropriate error is returned. Otherwise the sketch name is accepted. See https://arduino.github.io/arduino-cli/dev/sketch-specification/#sketch-folders-and-files
