Adds a code lens above datasets: and additional_datasets: lists with glob patterns, e.g. {dataset: '*', project: CMIP6, exp: historical, ensemble: 'r*i1p1f1'}, that replaces those entries by the datasets with data for every variable group that uses the list. The same command is offered as a code action on that line, for editors without code lenses such as Emacs with Eglot. Neither is offered in files that are not ESMValTool recipes.

• The values are found with the facet search used for completion, one facet at a time for all variable groups at once. ensemble and sub_experiment are expanded last, which reduces the number of searches: all CMIP6 historical r*i1p1f1 datasets for two variables take about 40 seconds instead of 3 minutes.
• Ensemble members are written as ranges with esmvalcore.dataset.datasets_to_recipe, and the entries are written as format_recipe writes them. Only the entries with glob patterns are edited; anchored entries and aliases are left alone.
• Progress is shown while searching, errors (e.g. no data, or a facet that cannot be searched) are shown as messages, and the edit is only applied if the recipe has not changed in the meantime.
• Needs a newer ESMValCore commit than the one in pixi.lock on main (for format_recipe), so pixi.lock is updated.

Known issue, not fixed here: the ESGF searches share intake-esgf's sqlite-backed requests cache between threads, and one large run logged sqlite3.InternalError: cannot reset statement.

Tested with pixi run test, pixi run test-vscode, pixi run pre-commit run --all-files, and against ESGF.
