[IMP] test_lint: adjust ES version for supported browsers

Coremastertest_lint

The testing rules for Odoo’s JavaScript code now align with the browsers currently supported by Odoo 14 and later. This allows teams to use newer browser capabilities already present in Odoo while dropping checks aimed at outdated Edge and older iOS versions.

Original PR description

This reverts commit d431f94c759f9811c640d81a274e90301276d001 and even upgrade the EcmaScript version further to ES10/2019. The original commit mainly targeted the support of MS Edge (pre-Chromium)…

This reverts commit d431f94c759f9811c640d81a274e90301276d001 and even
upgrade the EcmaScript version further to ES10/2019.

The original commit mainly targeted the support of MS Edge
(pre-Chromium) and earlier versions of iOS 11.

As with the release of Odoo 14, we don't support either of those (MS
Edge only Chromium-based and iOS 12), the original restriction can be
lifted and again target EcmaScript 9/2018.

But furthermore, some features of ES10/2019 are already in use in Odoo
14+ (e.g. `Object.fromEntries()` used in SpreadSheet, PoS, WebEditor,
Website Sale...) and the only browser not supporting them is Safari on
iOS versions < 12.2.

As there is no drop of supported devices between iOS 11 and 12 and they
all have access to - at least - the latest revision of iOS 12 (cf.
12.5), it looks reasonable to target the latest revision only and not
the earlier ones. This policy also matches the "ever-green-browsers"
policy applied on desktop.

Note: please note that the tool (es-check) used for testing the
EcmaScript version targeted has for primary goal to catch unsupported
syntax and reserved keywords only, but not the actual APIs available for
a given EcmaScript version. (e.g. async/await keywords or string
literals are tested *but not* Object.fromEntries() or
Array.prototype.flatMap()).
