[BUG]: Type definition uses regex as string literal type

[jendrikw]

Description

The new type definitions sometimes contain string literals of regexes as types. This does not work as expected.

Steps to reproduce

Notes

At least these types are affected (generated with grep -RF "'/^" plotly.js/):

plotly.js/src/types/generated/schema.d.ts:    anchor?: 'free' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    matches?: '/^x([2-9]|[1-9][0-9]+)?( domain)?$/' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    overlaying?: 'free' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    scaleanchor?: '/^x([2-9]|[1-9][0-9]+)?( domain)?$/' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/' | false;
plotly.js/src/types/generated/schema.d.ts:    axref?: 'pixel' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    ayref?: 'pixel' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    xref?: 'paper' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    yref?: 'paper' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    xref?: 'paper' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    yref?: 'paper' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    xref?: 'paper' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    yref?: 'paper' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/';
plotly.js/src/types/generated/schema.d.ts:    xref?: 'paper' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/' | ('paper' | '/^x([2-9]|[1-9][0-9]+)?( domain)?$/')[];
plotly.js/src/types/generated/schema.d.ts:    yref?: 'paper' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/' | ('paper' | '/^y([2-9]|[1-9][0-9]+)?( domain)?$/')[];

Some of these can be represented with template literal types: 'paper' | `x${number | ""}${" domain" | ""}`

Thanks for reporting this. A lot of the types are autogenerated, so likely an issue we can fix up in that code.
