fix: Update error to not indicate this 'usually' is due to deps

[jennifer-shehane]

User facing changelog

We updated the messaging when Cypress fails to start to be clearer that it’s not always due to a dependency missing.

Additional Details

• I see issues with this error message over and over. And most people mention that they have all dependencies - or they’re just running on a very normal machine and this happens.
• I’d like it to be clearer that this error may happen for other reasons and that they should just read the error message for more detail. I think people ignore the error message because we strongly infer that it’s due to a dependency issue.

Some example issues:

• cypress run exits with crashdump #17110
• Had to manually force install on Windows #16901
• Command failed with UNKNOWN #16647
• Cannot start on Ubuntu - /home/ubuntu/.cache/Cypress/7.2.0/Cypress/Cypress: 1: Syntax error: word unexpected (expecting ")") #16378
• Syntax Error "(" unexpected on Ubuntu 20.04 when running Cypress 6.3.0 #14725
• I stopped searching

Some example errors that are not due to missing deps

Command failed with UNKNOWN: C:\Users\EX13068\AppData\Local\Cypress\Cache\6.9.1\Cypress\Cypress.exe --smoke-test --ping=859
spawn UNKNOWN

#
# Fatal error in , line 0
#

Command was killed with SIGTRAP (Debugger breakpoint): /home/opensuse/.cache/Cypress/7.5.0/Cypress/Cypress --no-sandbox --smoke-test --ping=484

/home/ubuntu/.cache/Cypress/7.2.0/Cypress/Cypress: 1: Syntax error: word unexpected (expecting ")")

/home/robert/.cache/Cypress/6.3.0/Cypress/Cypress: 1: Syntax error: "(" unexpected

User experience

Before

Cypress failed to start.

This is usually caused by a missing library or dependency.
