fix(actions): Fix how jobs in matrixes are grouped (#38980) (#38998)

Backport #38980 

The workflow graph decided which job rows belonged to the same matrix by
parsing display names: it stripped a trailing `" (...)"` off `name` and
grouped rows sharing the prefix. That guesses at a string the user
controls, and it fails both ways. `jobparser` only appends the `
(<combination>)` suffix when `name:` contains no `${{ }}`, so a leg
named `E2E on ${{ matrix.browser }}` never grouped, while two unrelated
jobs `build (fast)` and `build (slow)` folded into one bogus matrix
panel.

Matrix legs already have a real identity: expansion clones one row per
combination, all sharing the workflow's `JobID` and differing only in
`Name`. Group on that instead, so a matrix is whatever the backend says
it is. Matrix expansion state is keyed on the graph node id for the same
reason.

Closes https://github.com/go-gitea/gitea/issues/38975, though that
report's own example already groups on main, since `explicit (${{
matrix.leg }})` interpolates to a name that still ends in a suffix. The
interpolated shapes above are the broken ones.
