Maybe stick to the old-style syntax for the regression tests?
The declarations that won't work as expected with older ICU versions
would be:

CREATE COLLATION case_insensitive (provider = icu, locale =
'und-u-ks-level2', deterministic = false);

'und-u-ks-level2' is equivalent to 'und@colStrength=secondary'

CREATE COLLATION ignore_accents (provider = icu, locale =
'und-u-ks-level1-kc-true', deterministic = false);

'und-u-ks-level1-kc-true' => 'und@colStrength=primary;colCaseLevel=yes'
