github: fix image-mint.yml syntax

[simondeziel]

Before that:

$ yamllint .github/workflows/image-mint.yml 
.github/workflows/image-mint.yml
  1:1       warning  missing document start "---"  (document-start)
  3:1       warning  truthy value should be one of [false, true]  (truthy)
  52:81     warning  line too long (93 > 80 characters)  (line-length)
  81:6      error    syntax error: expected <block end>, but found '<block sequence start>' (syntax)
  86:81     warning  line too long (110 > 80 characters)  (line-length)

After that adding the missing space:

$ yamllint .github/workflows/image-mint.yml 
.github/workflows/image-mint.yml
  1:1       warning  missing document start "---"  (document-start)
  3:1       warning  truthy value should be one of [false, true]  (truthy)
  52:81     warning  line too long (93 > 80 characters)  (line-length)
  86:81     warning  line too long (111 > 80 characters)  (line-length)

I was looking into it and couldn't spot it. Thanks!

Yeah, I used meld .github/workflows/image-{mint,ubuntu}.yml to spot the difference.

This speaks that we need a YAML linter in our CI.

Agree, that would help tremendously, especially with those workflow files.
