fix: use bold rather than backticks around command output

Checklist

=========

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have checked for similar issues and haven't found anything relevant.
• This is not a security issue (which should be reported here: https://circleci.com/security/)
• I have read Contribution Guidelines.

Internal Checklist

• I am requesting a review from my own team as well as the owning team
• I have a plan in place for the monitoring of the changes that I am making (this can include new monitors, logs to be aware of, etc...)

Changes

• Use color module to bold output of update command error

Rationale

Having backticks in the output of the error when update is disabled doesn't make as much since, since the backticks are rendered literally. Bolding the text probably is better visually.

Considerations

==============

I haven't figured out how to test this easily, or to force fatih/color to send control codes in test mode so that this can be tested.

[haven't functionally tested with the exact code, but should look roughly like this]

Here are some helpful tips you can follow when submitting a pull request:

1. Fork the repository and create your branch from main.
2. Run make build in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (make test).
5. The --debug flag is often helpful for debugging HTTP client requests and responses.
6. Format your code with gofmt.
7. Make sure your code lints (make lint). Note: This requires Docker to run inside a local job.

There's also:

circleci-cli/cmd/setup.go

Line 241 in 2259641

return errors.New("No existing host or token saved.\nThe proper format is `circleci setup --host HOST --token TOKEN --no-prompt")

this is missing the ending backtick anyway / also, but wondering if it would make sense to put the string in double quotes vs. bolding it (also not sure if it would work to bold the error directly?)

Something like (proposed):

diff --git a/cmd/setup.go b/cmd/setup.go
index 6a2d068..c9767b2 100644
--- a/cmd/setup.go
+++ b/cmd/setup.go
@@ -238,7 +238,7 @@ func setupNoPrompt(opts setupOptions) error {
 
 	// Throw an error if both flags are blank are blank!
 	if opts.host == "" && opts.token == "" {
-		return errors.New("No existing host or token saved.\nThe proper format is `circleci setup --host HOST --token TOKEN --no-prompt")
+		return errors.New("No existing host or token saved.\nThe proper format is \"circleci setup --host HOST --token TOKEN --no-prompt\"")
 	}
 
 	config := settings.Config{}

Thanks for this, it is, in fact, much clearer. Your proposition is also interesting!
