while merging 3.2 into master, I noticed that `testCanParseVeryLongValue` is triggering this error on master, due to this regexp that we added for handling yaml tags. This regexp needs to be fixed so that we can merge the test case.

This is a second fix for the issue discussed in #20411. My first PR (#21279) didn't fix the bug in all cases, sorry.
If a YAML string has too many spaces in the value, it can trigger a `PREG_BACKTRACK_LIMIT_ERROR` error in the Yaml parser.
There should be no behavioural change other than the bug fix
I have included a test which fails before this fix and passes after this fix.
I have also added checks that detect other PCRE internal errors and throw a more descriptive exception. Before this patch, the YAML engine would often give incorrect results, rather than throwing, on a PCRE `PREG_BACKTRACK_LIMIT_ERROR` error.

[Console] [SymfonyStyle] Replace long word wrapping test to directly test output
Since the parser is able to return `\DateTime` instances when the
`Yaml::PARSE_DATETIME` flag is passed, we need to ensure that the parsed
value actually is a string before passing the parsed value to string
functions.
