Fix problem with regular expression to grab go version from go.mod

[trevorackerman]

parse-legacy-file against a go.mod file with the directive

go 1.x.y

is not honoring the version of go specified in go.mod.
It is calculating GOLANG_VERSION to be 1 in function get_legacy_version()

The regular expression needs to include . characters in addition to digits.

Tested this with gnu sed version 4.9 and builtin sed on MacOS 15.6

Note

Adjusts the sed regex in get_legacy_version to include dots when extracting the Go version from go.mod/go.work directives.

• Scripts:
  • Update bin/parse-legacy-file → get_legacy_version to widen the sed match from s/go([0-9]+).*/\1/ to s/go([0-9]+.).*/\1/, enabling extraction of dotted Go versions from go.mod/go.work go directives.
