[BUGFIX] Raise doctrine/lexer:"^1.2.2"

doctrine/lexer has released a new minor version with changed
method docblocks, which now emits phpstan errors because of
incompatible types.

This patch raises the minor version for development and core
usage and adding phpstan ignore pattern to the baseline file
until doctrine/lexer has fixed the incompatible state. This
is a dedicated preparation to raise other dev dependencies.

Issue has been reported to the corresponding github repository:
https://github.com/doctrine/lexer/issues/62

used commands:

> composer req doctrine/lexer:"^1.2.2"
> composer req doctrine/lexer:"^1.2.2" \
  --no-update -d typo3/sysext/core
> Build/Scripts/runTests.sh \
  -s phpstanGenerateBaseline
