Month threshold is not used when rounding years

**Describe the bug**
Having set month and year thresholds for the relative time plugin, the monthly threshold is not used for rounding values greater than 1 year.

``` Javascript
import dayjs from "dayjs";
import relativeTime from "dayjs/plugin/relativeTime";
import updateLocale from "dayjs/plugin/updateLocale";

const strictThresholds = [
{ l: "M", r: 1 },
{ l: "MM", r: 11, d: "month" },
{ l: "y", r: 1 },
{ l: "yy", d: "year" }
];

dayjs.extend(relativeTime, { thresholds: strictThresholds });
dayjs.extend(updateLocale);
dayjs.updateLocale("en", {
relativeTime: {
M: "1 month",
MM: "%d months",
y: "1 year",
yy: "%d years"
}
});

const TODAY = "2023-02-07";
const tenMonthsAgo = dayjs(TODAY).from(dayjs("2022-04-16"), true); // 10 months
const twentyTwoMonthsAgo = dayjs(TODAY).from(dayjs("2021-04-16"), true); // 2 years -- should be 1 year
const thirtyFourMonthsAgo = dayjs(TODAY).from(dayjs("2020-04-16"), true); // 3 years -- should be 2 years

```

**Expected behavior**
The rounding of values for years should use the monthly threshold.

**Information**
- Day.js Version: 1.11.7
- OS: IOS
- Time zone: GMT-07:00 DST (Pacific Daylight Time)

Start by running the provided relativeTime plugin reproduction with the strictThresholds configuration and inspect the relativeTime plugin entry point. Verify how month and year values are rounded for 22 and 34 months; done means the examples return 1 year and 2 years while the 10-month case remains 10 months.
