enhance(actions): improve matrix job titles, bump actionslib (#39485)

Bump actionslib to v1.3.0 and format matrix job titles like GitHub.

- Matrix values are listed in declaration order, nested arrays and
objects are flattened, null and empty values are skipped
- Expression-evaluated names are trimmed and fall back to the job ID
when blank
- Matrix `include` and `exclude` match keys case-insensitively and
coerce numbers like GitHub

| Matrix | Before | After |
|---|---|---|
| `v: ["a,b"]` | `job (a,b)` | `job (a,b)` |
| `v: ["a, b"]` | `job (a, b)` | `job (a, b)` |
| `v: [[a, b]]` | `job ([a b])` | `job (a, b)` |
| `os: [x], arch: [y]` | `job (y, x)` | `job (x, y)` |
| `v: [{t: a, p: "b,c"}]` | `job (map[p:b,c t:a])` | `job (a, b,c)` |
| `v: [{t: a, p: [b, c]}]` | `job (map[p:[b c] t:a])` | `job (a, b, c)`
|
