The function isTty() in Streams.php returns wrong information.
If the output is to an TTY then it returns false and if the output is a pipe or file it returns true, it should be the other way around.

The `E_STRICT` constant is deprecated as of PHP 8.4 and will be removed in PHP 9.0 (commit went in today).

The error level hasn't been in use since PHP 8.0 anyway and was only barely still used in PHP 7.x, so removing the exclusion from the `error_reporting()` setting in the example code shouldn't really make any difference in practice.

Before this code tried to replace newlines with empty spaces, but it
didn't always work because the new value would only use the replaced
string if additional wrapping needed to be done due to size constraints.
This updates the code to properly handle new lines in all content by
creating an extra row for each one, using the same logic that already
existed for wrapping longer content.

See wp-cli/entity-command#262 for an example
of the currently broken behavior that this PR fixes

* Replace tabs in tables with 4 spaces

* Move to `padColumn`

* Cast to string

This adds the same functionality from both #179 and #181 to the tabular
table output. In WP CLI behat tests, the 'table containing rows' check
can only use tabular output so we need to fix it here in order for tests
to work.

Previously the final table output was trimmed with the intention of
removing the last newline. This had an unintended side effect of
removing the tab characters from empty columns in the specific case
where the last row had one or more empty columns at the end of the row.
This makes sure we are only removing the newline character as intended.

Add a new unit test to verify this behavior as well.

To avoid deprecation warnings in newer PHP:
```
PHP Deprecated:  str_replace(): Passing null to parameter #3 ($subject)
of type array|string is deprecated in
/Users/isla/source/wp-cli-dev/php-cli-tools/lib/cli/table/Tabular.php on
line 30
```

…juncts (#189)
